Good, but not great.
This game is a great idea, but way to easy. Once you get the duelies you can just stand in the middle, and use one hand to aim and one hand to click really fast so you shoot really fast so you're unstoppable. I love the idea, maybe if you added new enemies like clones carrying armor and weapons, or dead clone corpses can still take bullets until you gain even better weapons, obviously add more weapons (e.g: AK-47, Laser Gun which could shoot through multiple enemies etc), add new "moves" such as holding the chainsaw out and being able to spribnt through groups of enemies, and finally give make it a wider area so sort of side scroller but within a limited idea.
