This was awesome! Love the concept, the sound effects were so fun and in general it was fun to play. The art direction is solid and reminds me of Earthworm Jim! Very endearing overall.
I noticed some consistency issues - for example sometimes you can jump over enemies and sometimes you can't - and when you touch the sprite of an enemy that's not on the same level as you (e.g. they're in a pit and you're not) you still die. I still think this was a great entry though, great job!
