The game is really good, i like the graphics and audio... controls are also very precise and satisfying!
Difficulty may be a little too rough for casuals (I died A LOT), but that's no problem if you are targeting hardcore players. Also when you played through the level you don't have to figure it out anymore, which was a bit frustrating at first... But I can imagine that some speedrunners will love it.
A little time before the level restarts would make me feel a little less rushed... and maybe help to understand why I failed.
But that's just a tiny criticism! The game is very cool, i like it
