The game on it's own purpose is great, nice music, sfx and graphics, but I think that it's not fun, i mean there's not lot of things, you pop some bubbles, you saw that the game it's "only this" and pass to next. add something to do with the points: make appear more valueable/resistent bubles, give yo new types of shot, and so on.
(I know that we had a short period to do the game, don't having time to do all this, but I'm trying give some feedback to improve the game after the jam posteriorly)
