❄ Great concept! I don't know that I've seen anything quite like this. With some polish and fine tuning, I could see this doing well on mobile platforms, though the difficulty might be something to adjust
I found the time limits on levels to be quite frustrating however perhaps it could be replaced a timer that tracked how long a player took to complete the level? It might encourage players to get better at herding the bubbles without making the game technically any easier, and without creating that sense of frustration.
Otherwise the art is very nice and the music creates a nice calming atmosphere that's only hurt by the time limits, keep up the good work!
