Good game! A good stress reliever
Simple gameplay, explosions...uhh...more explosions. What can I say, this game is a great arcade shooter.
Like the previous poster said, bouncing back and forth off the walls is a fairly good tactic...that is of course until you get to the electified wall level. I stopped playing after I saw "Objective: Survive for 10 Minutes," I would have kept playing but my fingers needed a rest.
Some things to add for perhaps a sequal:
-More powerups: I.E. Increased speed, slower enemies, different guns
-A save feature: Even though I'll play this game again, I'd like to start over where I left off instead of fighting through those timed missions again.
Anyway, nice game you've got here. All my 5 R belong to this!
