This is quite a fun game if you are willing to put a little time into it, as there is no save points and a seemingly endless world to explore. Destroy enemies and collect the bubbles that they drop to upgrade your bubble tank. Enemies get more difficult as you get farther away from the starting point, so develop a strategy that doesn't involve you getting out to a point where the enemies are too difficult for you. Have fun and good luck!
