This one has some potential
You got a pretty fun game, a nice twitchy one.
The blood was awesome, really nice. More weapons are a must, this is the kind of game where the more, the better. Difficulty was a bit of a problem, but this is one of those games where everything has to be timed down in the player's head, which is usually a bad thing, but this game has so much potential that it's a good thing it's so complex.
I am a bit scarred about the final version being one of those impossable shooters, but In that case, I'm gonna beat the whole thing just for the nice story and to tell everyone I did. The hardness actually opens up a new door for competitiveness. Like I said, if this game was any worse, I wouldn't even bother, but you did a nice job balencing it, Great job!
