well on thing
great game but one thing..... why does your tank stop growing after a certain point? if you can collect more bubbles the tank should grow.. maybe to the size of an entire bubble (who knows)
also you should have a map to tell you which bubbles you have been in that way wyou can clear the entire map .
and MAKE A DANG ENDING FOR THE GAME.
but other than that good game. kept me entertained (well the part when your ship grows)
