The art and aesthetics are nice! Music is very dreamy and relaxing, feels "floaty" like the balloon itself so I think it captured the essence of the game well.
A bit challenging like the others have said, though I think that might be part of the appeal of the game (e.g.,, it's similar challenging yet addictive mechanics as Flappy Bird).
I was wondering what item was giving me the sudden speed boost? I'm curious if that was supposed to benefit me or hurt me, as I found it made me die easily (as I would ram into other balloons).
Thanks for sharing!!
