Great shooting game
It's action packed, never becomes boring, although near the end it get's hard but maybe that's because of my rushing mentality as well.
One thing i would like to see in the next version (or this one) is wasd option and assign space to a melee weapon like a knife so you can stab enemies that are up close and thus saving your ammo (and normaly a melee weapon is super strong thus saving time as well).
