Willy in the Islands of Mystery : Part II : The Temple

---

Hello everyone

I am thrilled to announce the release of my sixth game, "Willy in the Islands of Mystery: Part II: The Temple."

It uses the JSW64 engine with the variant [].

This game is a direct sequel to the first game, "Willy in the Islands of Mystery: Part I; Exploration," created in 2007.

I encourage you to start by playing Part I.
It is available for download via this link:

Part I, "Exploration":

The story: For some unknown reason—perhaps after the sinking of his cruise ship—Willy is alone on a raft in the middle of the ocean. One morning, he discovers a mysterious island on the horizon. He will have to explore it and find a way back home...

Part II, "The Temple,"

Begins in the exact same room where Willy finished the game in Part I.
The story: After exploring the islands, Willy discovers an ancient temple. To leave the Isles of Mystery, he must face its dangers and collect all the flashing objects scattered inside. Perhaps the Temple holds the key to his freedom.

Part II, "The Temple," has many surprises in store for you.

Technically, it's the first JSW game with different music for each room.
The theme is therefore different depending on the room.

This game also has many effects that greatly enhance the game's atmosphere.
I won't say any more; you'll have to discover it all for yourself...

And I've saved the best for last: I didn't create this game alone. Daniel (JetSetDanny) worked incredibly hard on all these improvements: music programming, visual effects, adding traps, scrolling messages, loading screen, end screen, game translation, title colors, complete testing, promoting the game on social media and websites dedicated to classic games… I think I'm forgetting some things, and I apologize to him.

It was a colossal and time-consuming undertaking. I want to thank him for his dedication and availability.

This is why this game is co-signed (Hervé and Daniel), as you can see on the home screen.

The game is available in two languages: English and French, In TAP and TZX formats

Have fun!   

Hervé

First of all, I want to congratulate Hervé on the release of his sixth JSW game and thank him for making the second part of Willy in the Islands of Mystery!

Secondly, I want to thank him very much for adding my name to the title screen. It’s a great honour for me! I’m only a little worried that it may lead to some confusion regarding credits for The Temple. From my perspective, Hervé should always be listed as the (sole) author of the game, and if someone feels a need to mention my contribution, it could be done somewhere on the side, in fine print, and describing it precisely with these words: "contribution" to Hervé’s beautiful game.

I would like to share more info and reflections about The Temple, but if it gets too long and becomes boring to some people, I will say this: Don’t bother reading it if you’re not interested, but do download and play Willy in the Islands of Mystery. Part II: The Temple. It’s a beautiful, atmospheric game, it’s relatively easy, and it allows for what I believe is a favourite activity for many fans: exploring the game, just roaming around in this fascinating temple on a mysterious island that Hervé has created.

OK, so now, for those who might be interested, some background. As you probably know, Hervé is the author of four excellent JSW games released between 2005 and 2007: Jet Set Willy in Paris, Willy on a Transatlantic Cruise, Escape of the Snails and Willy in the Islands of Mystery. Part I: Exploration. That last game explicitly invited the player, at the end, to play Part II of the game, called The Temple. Sadly for me—and I’m sure for a lot of other fans—that second part never materialised in that era, and Hervé stopped being active on the JSW scene.

I did hope that he would come back one day and release The Temple, as well as create his other JSW projects—there were several that he mentioned by name and gave some information about. So it was a great joy for me when he joined this forum in January 2025 and announced that he was back on the scene! 😁

Hervé sent me a file with The Temple in early March 2025. I playtested it and suggested just a couple of minor improvements, which he made. At this point the game was practically ready to be released: 64 new rooms, designed in Hervé’s beautiful, atmospheric style, with various references to aliens, Yetis, etc., typical of his earlier projects. It would already have been a great comeback game, but I wanted to make it even more special and asked Hervé to let me add some elements to it, and he kindly agreed. This is why the game wasn’t released earlier. Since I was committed to other projects, I only started working on The Temple in earnest in August. By that time, Hervé had already made his comeback game release, launching the also excellent Welcome to Willy’s Fun Park!.

My main idea for enriching The Temple was to code new music for it and allow the game to have varied music in various groups of rooms. This was something that I had done as a contribution to several games by other authors in recent years (please see this thread if you’re interested), but they were all games using the original JSW game engine (which has come to be known as JSW48, to differentiate it from the later 128K game engines) and its music system. My idea was to put into practice the same principle for 128K games, and indeed The Temple is the very first JSW64 engine game ever that features a selection of in-game tunes (no tune plays in more than four rooms; some rooms have individual tunes related to their particular character). I hope that this does enrich the playing experience as far as audio is concerned.

I have also added some special effects to each room using the so-called Patch Vectors (PVs) — pieces of code written especially for the room in question, either (or both) as room-entry PVs (which only kick in once after entering the room) or runtime PVs (which run every time the program goes through the loop). Working on the PVs was a very interesting coding experience for me; I did learn a lot in the process.

So now everyone interested can enjoy the second part of Willy in the Islands of Mystery and, as Hervé has mentioned, if you haven’t played it yet, do start with the first part of the game, Exploration, which can be downloaded either from its home page on JSW Corner that Hervé has already indicated or from its page on JSW Central.

The Temple has so far been released in English and French. More language versions will be created and released in the near future.

And a really wonderful thing is that Hervé is back and working on other projects that I'm sure will be released next year (in 2026) and in the following years ☺️.

So download, play and enjoy The Temple! 😊

Wonderful! I'm currently working my way through Part I, which has blown my mind with the lush graphics and clever traps... I really feel like I'm on the island!

I'm looking forward to tryung the temple. I'm glad to hear that it's relatively easy as this will be my first attempt at a JSW game without the aid of a map. Can't wait!

[jetsetdanny]

Mike, I wrote about the game being "relatively easy", and I owe you an explanatory note here:

There is a huge difference in the perception of the difficulty of games depending on whether one plays them using some kind of "assistive tools" - like an Infinite Lives POKE or saving and loading snapshots, or using the Rollback feature while recording. The latter two are more powerful than an Infinite Lives POKE, because that POKE only protects you from "simple" loss of life, but not from Multiple Death Scenarios (when you keep losing lives continuously, e.g. like falling down to "Entrance to Hades" in the original JSW).

These days I always play using the Rollback feature (which allows you to roll back to a previously marked cue point, so an earlier moment in the game, before you ran into trouble). If I lose a life, I roll the game back to an earlier point, no worries. Because of this, my estimation of the difficulty level of games varies drastically from the opinions of people who play without this or even without infinite lives: they often describe as very difficult what seems very easy to me.

Well, you'll judge for yourself how much my description matches your reality 🙂.

And do you use any "assistive tools" when you play JSW games, by the way?

P.S. *Really* difficult games are difficult even if you play using Rollback or saving and loading snapshots. They would be absolutely impossible for a human to solve with 7, 70 or perhaps even 700 spare lives.

[MikeH]

Yes, I'm definitely using lots of save states on my little handheld when playing. I save every time I'm about to enter a new room (you never know what's in there) or when I've just done a tricky bit that I don't feel like having to do again if I lose a life.

Funnily enough, when I first started watching your playthroughs on YouTube to help me when I got stuck, I just assumed that you were a really, really good player and could not only remember the ideal route through every map, but also execute it flawlessly each time 😂. I'm sure you are a very good player aside from that. But it was a bit of a relief to read that you use the rollback feature when recording the videos!

Nevertheless, I think the Temple will be a bit of a challenge for me as I won't have a map to rely on. I'm just about finishing up Part I now, so I'm looking forward to seeing what's in store. I think 64 rooms is a bit more on the manageable side.

[MikeH]

End of Part I 

Roll on Part II 🥳

[jetsetdanny]

Congratulations!!! 😁👏🍾🎉

[MikeH]

I finished The Temple. It's such a great game! It was totally doable even without a map, although some of the puzzles had me scratching my head for a while....

Also, there's a genuinely wonderful moment that made me laugh out loud in surprise 🙂

I'm probably gonna give London or Paris a go next.

[jetsetdanny]

Thanks for playing and finishing The Temple, Mike, and for telling us about it! I believe you are the first person in the world other than Hervé or myself that is known to have completed The Temple! 👍😁

I would kindly suggest that you have a go at "Jet Set Willy in Paris" next, as "Jet Set Willy in London" is... still on Hervé's side of the screen. It will be released later this year, hopefully 😊.

Oh, and what is this genuinely wonderful moment that made you laugh out loud in surprise? 🤔

[MikeH]

I actually fancied a bit more exotic scenery so I've gone for Transatlantic Cruise rather than Paris! I'm a little way in and still haven't consulted a map. Although I note that it's 128 rooms, rather than the right 64 of Temple, so I don't know if I'll be able to hold out til the end.

The part in Temple that gave me a pleasant surprise was a reference to a certain game 😉
