-maybe its because im on keyboard but the controls are too binary for a platformer especially with precise platforms (or would have needed a shadow to know if you're above the platform)
-weird variations in speed and jump intensity? is there a mechanic where you get faster and faster as you keep moving?
-the tower warping effect is cool conceptually but make it both really hard to know how high you're gonna jump and where you can go next (i got lucky and saw a video you posted about this part on discord during devellopment but otherwise i would have never guessed)
also watch out about thin platforms, its by definition a challenging element, so add on top of it the two previous point and it raise the difficulty by a lot :/ (same for platforming above the void and timed platforms)
