Wow the game looks really nice and the music is great! Really like the concept of bouncing around including on walls!
However, it felt to me that the game was really too fast, which made it hard to control sometimes. Also, it is not clear how we need to sync our bouncing with (the rythm in the music follows some patterns, if we hit on strong times, nothing really happens; even tapping the beat does not seem to work... the sync seems a little broken =p). Maybe try to add some clear visual indicators during the time window the player is allowed to bounce. I had to spam the spacebar to be able to jump and bounce lol
But the fun concept, and JUICE, and overall atmosphere did compensate a lot for these problems !!
Really good job!
