whoa. WHOA. Thanks for noticing. I uploaded an old version, which is very much work in progress. There's even no objectives! I'll try to contact admins and get permission to reupload...
Meanwhile, I understand the problem with the controls - the bubble mechanic is quite wonky. However we did take this into account when designing levels, and the few bits (3 to be precise) where bubble is required we tried to make it easy, with room for error. It's more for fun and speedrunning :)
