Not the best game I've played.
I like the concept, but it's full of opinionated flaws. The character's speed is quite slow, and the shooting is too precise, you should aim for general direction instead of having to get the crosshairs directly on the creatures. The music is annoying and repetitive, but you can always just mute that. It's quite violent, but it's mostly fake violence, I can't sense an ounce of realisim. As for the work, however, great animating, just work on the graphics themselves.
