Nice game! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

It crashes when loading the last level, I didn't have time to test that one and the file had a syntax error

I have a fixed version now, but I won't upload it until voting is over

Cool entry! My one complaint about the puzzles is that I found the second level to be really confusing at first because there's nothing to indicate that you would need two keys to progress.

After I solved the puzzle with the ghost and the arrows, the application closed. Is that where the game ends or did it crash?

Huh, I didn't notice that, looks like you have to choose the resize window option or click maximize, just clicking on the corner isn't enough (On windows 10, at least)

Very cool concept, I would love to see this explored further!

I played the Windows version and I was unable to find any way to scale the window! I had to play on a very tiny screen :(
