Wow, what a stellar little game! The controls felt really great to me, and the level design is really excellent. I especially liked your approach to boss battles, they were challenging but not gruielling since your efforts were cumulative; perfect for a jam to give a real challenge while still allowing the player to progress and see all of what you made! Unfortunately I think my game crashed when i reached the door at the top, but I really loved my time here. Great work!!
