Having a full installer for your game is pretty intense for a game jam game. I was kinda sketched out and almost didn't play it as a result, I suggest uploading a different type of build for future jams.
Overall, the game was interesting. The platforming felt alright and it definitely fit the theme. I got random room number 1 and was very confused by what the purpose of it was.
If you wanted to improve, I suggest adding more animations to the player character instead of the background elements.
Overall, a very interesting experience.
