A very nice game ! Graphics are good, sound and music too, controls is precise, my only advice is to work a little bit your difficulty ramp, I get that it's supposed to be a hard game but try lower the difficulty at the start of the game... I didn't go further the first trampoline, but if I have the time I'll get more into it ! (And, for the music try a AudioStreamPlayer instead of an AudioStreamPlayer2D, like that we won't have the music just in one ear)
