Love it!!
This is a great game, the graphics are amazing and give a good feel to it, the shooting is challenging and fun, theres a good variety of weapons and enemies and theres no annoying music. Some things i would consider adding into another version are enemies that can shoot (and miss), maybe some form of explosive, blood and gore, dual wield with certain weapons (like pistols etc.), body armour and a pause button. Maybe the ability to walk around would be a good idea but it might change the gameplay somewhat and i think its fun how it is, maybe, in fact definately, make more enemies of different shapes and sizes etc. that do different actions like jump, crouch, lie down, and go in different directions. I really like this game and you could make something really good out of it, can't wait to see the sequel.
10/10, 5/5
