Was fun! Got to current end of game. Mechanics were clear and all seemed to work smoothly. Arts good, I especially like the backgrounds.
Im kind of confused what the difference between the strength/health bar are. Does strength have an effect beyond changing health? Having to press a key to pick up items, activate the speed boosts, and eat all kind of feel like busy work that could be done automatically. With that said, there where moments where speeding along and timing the right keys and the right time had a nice rhythm to it so it really depends what your going for.
The time till you fall through a platform when pressing down seems long. Unless there is some other use for pressing the down button I didnt catch, could you not just make it so you fall through the platform the moment you press the down key?
Played on linux, ran into no glitches.
Thanks for the demo!
