nice game, I jsut fail to do the bubble floating that likely is intended. I solved it by doing jumps from bubbles upwards.
Hiya! Lead developer here. If you're jumping above a bubble after throwing it, making a "staircase" upwards, that's actually intended!
It's a kind-of timing based technique we call "Bubble Jump".
When jumping and releasing a bubble, the bubble actually spawn a bit below of where you would normally spawn it to facilitate this trick. Hopefully it wasn't much of a problem!
