Wonderful!
This game was very entertaining. I have found numerous good things about it and not many bad things, so here they are.
THE GOOD:
-Smooth gameplay. The character was very simple to control and aiming was not a problem, as it is with a lot of flash shooters.
-Easy to pick up on. I'm not usually one to play shooters, so I know from experience how hard it can be to learn a new game and be able to really play it. Any beginner (such as myself) can just pick up this game and have a lot of fun.
-Logical progression of difficulty. Even I was able to start the "Defense Mode" of the game and not have an excessive amount of trouble adapting to the new enemies. There were not too many, and I still haven't died yet (11:00 3rd day). The game was not too easy as to bore one, but was also not too difficult as to be very frustrating. The game has a very paced increase in difficulty, paired almost perfectly with how much experience you gain per level.
-Great sound! The ambient noise in the background was very haunting, and definitely added to the mood. The guns' sounds were all very different, and all fit the weapons well, making one feel more like the game is something almost possible rather than just another zombie game.
THE BAD:
-Too much blood. Even if it is "realistic", there was simply too much gore to be able to see what your character is doing at some times. The gore-colored monsters were a mean touch.
THE UNINTENTIONAL?
-I've found an easy way to get over 10,000 exp per level in the early stages of the game. Was this intentional, or was it just an odd quirk in the game's design? I'm not revealing my not-so-secret secret on here, lest many others see it, but if you don't know what I'm talking about feel free to PM me.
OVERALL: A very fun, easy-to-learn game, with only a few minor complaints.
Keep up the great work!
