Spooky! Impossible indoor spaces like this are inherently kind of scary, and that's a good opportunity to deploy random(ish?) level generation. The gradual addition of other dangers and monsters works well too. And I like the art style, it's got just the right level of detail. Well done!
As others have noted, Godot lets you export to a lot of different platforms, so I'd have loved to see a Linux build too. But the Windows one runs fine, so no big thing.
