Could have been better.
I'll go ahead and get the bad part of this review done. One of the problems was the fact that no matter what weapon you used, they all did the same amount of damage. Also, there was no challenge at all. Most of the time, the enemies grouped together, so they were all killed at pretty much the same time.
I don't even think it's possible to die in this game without standing still. If you decide to make a game similar to this in the future, I think it would be more well received, if you fixed the problems, and maybe added some non-melee weapons as well.
Now that we have that out of the way, let's look at the positives of it. For starters, it did help me pass about 10 minutes of boredom, and it's really not a terrible game. I think you did a decent job on it, so I'd like to see more games from you in the future.
All in all, i've played worse, and i've played better.
