What I liked:
- The overly happy music
- that the robot becomes your enemy in the end if you don't have all the keys. That makes the music fit as you knew something was wrong all the time
- the character controller allows for good dodging which is helpful with this kind of game
What I didn't like:
- That your key for actions is Z . As there are multiple keyboard layouts on some of them Z located on really awkward positions. Using non-letter keys is better.
- the level design lost quality with every level
