I really liked the sound design for this especially. The jump and landing sounds were really satisfying. At first, I didn't realize I had a triple because I was jumping too late and didn't end up jumping off the platforms so I though the game was too difficult, but after realizing I had a triple jump it was a really nice, relaxing experience lol.
The only suggestion I'd make is that fading out the alpha for the platforms is good, but isn't the greatest visual feedback for the timing of when the collider actually disappears. Having them fade in is good though so you can plan your next move, but I think having some kind of countdown would allow players to know when to jump so they can maximize their distance.
