Grats on completing your game jam entry! I just finished - I thought it had some good puzzling mechanics to it! I didn't realise I could go through the door in the first level, so ended up somehow using the stairs to get past! This meant I didn't quite learn the lesson I was meant to learn, but I picked it up by the 2nd and 3rd level! It'd be interesting if you could build the platforming mechanics to be more complex and interesting for the player - the puzzle were interesting, just could be cool with a more skill-based jumping / timing etc. Thanks for taking part!
Note: After completing, I replayed first level, and when I got to the second level - the enemy was just stuck in the door (and a smaller size than usual). So I think that was a bug :)
