I always dig for cute design like this and i finished all the 4 levels, i have some observation to make:
- Tutorial should not be textual, it could be better to have some example images on signboards.
- the zoom out camera at restart is bugged, make sure to do it once at level.
- Enemy sometime just fall trough terrain you (the first level featuring enemy should be 3 or 4)
- The spinning for now is clunky, this wasn't a problem until i had to run away from the boss, if you aim to see speed runner performance i suggest to keep free movement while charging, it should smooth the gameplay.
i hope to see the final version one day.
