Very fun game. Though i wish there was a way to gain more lives or a continue system cuz i held out until wave 12 and wanted to see what the rest of the game has to offer, and i dont think i can replay the whole game to that point sorry d;. The controls are a bit strange, would've preferred if z to shoot and shift to strafe instead of s and x so they would be easier on the fingers. Still liked it a lot though.
