Thanks for giving it a shot and I'm glad you enjoyed the gameplay! Admittedly, my playtesting was done very haphazardly and I burnt out hard by the end. There's a lot of polish I wish I could've added - but considering this is my first game jam, it could've gone much worse.
In retrospect, I probably should've had a mini tutorial that you could ignore (like words that'd show up at the bottom of the screen in the first room) in the first room. Or added a text pop-up when you're near the blackboards on the title-screen (which could tell you how to play in more explicit terms).
