This one was quite interesting, forcing the player to think about how much time they have to get to the next platform and whether they'll be able to reset in time. I think my main issue was that the main character did not have a shadow on blocks, which meant that it was very difficult to see where I would land, and I would often over or undershoot... I also never used the dash, as double-tapping is quite unwieldy. I would probably make the dash a separate button, such as F or E.
