Very good game! The screenshake, the gunplay, everything felt so satisfying! I'd like to see this game expand more! Clever title too :)
The only elements I didn't like were the sound and some parts of the screenshake. The screenshake did make me dizzy at some parts of the game and the sound especially in the "GET REVENGE" text were a little too loud.
Nonethless, very good game and I give this a 9.5 / 10
