This is interesting, but I'm not sure it's quite polished. You move by using recoil on the weapons you're using, but you only have three weapons, and they can "run out" of ammo and need to be recharged. This kind of makes movement tedious - since there are only two consistent ways of moving yourself (bazooka & squirt gun), you have to choose between going into a fight with a very powerful weapon very slowly or moving around the map very fast, with very little control. I'm not sure that I love that trade off.
