Yeah, our team had a huge technical difficulties at the end of making the project - merge conflicts, merge stompings, and github did not want to connect us to the server at the very last possible minute - making us not able to playtest properly. We want to continue the development of this game, hence your inout is extremely valuable!
The tip on the bubble is to not move the player until the bubble is at its highest point to jump over the obstacle :D Moving the player bursts the bubble!
