You've had tons of feedback already so I don't want to repeat any of that. Platformers are definitely my weakest genre in games haha, it took me like 5-6 attempts to make that jump. So my only wish would be restart the level and not have to return to main menu.
I think it'd be really cool if the player shrunk after using abilities or just jumping so that you can add the loop of eating > growing > shrinking. Another thing to make the jump feel a bit better would be "coyote time". I had no idea that existed when I made my platformer but it certainly helps those that aren't as skilled at platform *cough* me *cough* :).
