Good game, could be much better. Do some more different enemies, give the character more skills, not only different weapons. But in general: good game, the arena is just the good size, you're free to move but it's not too big. 4/5
Dude, it's so annoying, finally upgraded the tank, then I went into a bubble, got shot at by some kind of machine gun, and I had to gain all bubbles again to gain my double shooter :S
