The game is really fun, and hard. At times it felt like I needed to use muscle memory, and not just react to what was happening on the screen. Some parts were hard to figure out, I think having some sort of collectibles making a path would be helpful. They could give you points, or freeze the time or something. I understand the stages are really short, but I still wish there were some checkpoints. Then again, I saw myself improving, so if it's one of those games where you rage until you get better, then they may not be needed. It depends on what kind of game you are going for.
The movement felt good. I really like how your dash speedlines look, although I personally would prefer to always dash in the direction the camera is facing, and not the character.
Even though I was getting better at your game I was nowhere near your expected times. I strongly related to the feeling of being too good at your own game, and having a hard time judging how difficult it is going to be for other people.
