Controls are really tight. I appreciate the speed of the animations in keeping with the hardcore pace of the game. This is a very specific type of game, with a specific niche, but there's definitely an audience for this kind of thing. I don't necessarily agree with the comments saying to make it easier, but this definitely isn't, nor should it be, as mass crowd pleaser type of game. Could definitely use some in-game tutorialization to at least introduce you to which characters can deal with which obstacles though.
With these kinds of games though, I think presentation is a huge part of what makes or breaks them. It's important to be able to get players into a trance-like flow state, and the art and music will play a huge part in that if you keep iterating on this project.
