Cool game :) I loved the world that you have created and I especially liked how some enemies shot bombs that would stick to you like other items did. In terms of feedback, I think that the game would have been better if a little more time had been spent on general polish, even if that meant the world had to be smaller. Things like improving the player movement, teaching the game better (whether that be through a tutorial or careful introduction of mechanics) and better sound balance. (SFX seemed quite loud compared to the music)
Generally, I have found that smaller-scope, extremely polished jam games end up better than bigger, but less polished games. Good job overall though, I had fun playing!
