This game was very enjoyable and the premise, controls and gameplay are very simple however the amount of blood that splatters on the screen after killing a zombie makes the game very laggy you should tone down the amount blood that shows up on screen after killing on enemy to prevents this or get rid of the blood particles all together. The rage mechanic is pretty cool however I don't like the fact that your character moves on it's own, but that's just me. Also this game could have more variety in things to do and upgrades, also adding different enemy types can make it more challenging.
