I've updated the game, this is what it looks like now. It looks slightly off on my grandma's old Windows 7 laptop (i had to use it to make the edits, not joking. This is a slow piece of junk and even my grandma knows it.) but on higher resolutions it should look great.
I've also fixed an issue where if the game is running slowly and Willy walks into another room, he might fall into the room below before the game properly loads the new room.
Unfortunately the constant update of guardians is tied to rendering, and if they aren't rendered they'll freeze in place. I'll fix it some other day, because it's hell editing code on this computer.
