simple fun, and easy
this is a great idea, but you could expand on it. this game is much to easy though. and the new bubbles after metal are useless. thier just a little extra something to try. all you need to do is jsut use metal bubbles. you should create more objects that need to be used bhy poison bubbles or explosive bubbles maybe, and the shockwave bubble? wasent really worth using it didnt really help. but overall its a great game but its too easy and it does get boring after a while.
