Great job on this one! Levels were short and respawn quick, that held frustration down. The game is quite difficult! I think hitboxes are a tad off, I'm sure I didn't get hit every time I died. In the end I couldn't complete the level where story started picking up. I'm intrigued how it ended.
Suggestion: maybe holding A and W should propel you direct upwards (as they control corresponding propels that would be logical). If it feels too easy, maybe have it work for a short period of time. Also some particle effects for getting hit would be nice.
