Just like Crimson Land
I like this game a lot but I do think it could use some improvements.
1. Decrease the power of the Desert Eagle. I got the Desert Eagle and the Overkill ability and the game was over. I could easily get 10000 EXP in one round pretty early on in the game.
2. Add more weapons and skills. How about some rocket launchers? Flame Throwers?
3. Find a way to make it easier to see the zombies amidst the blood and gore strewn surroundings.
This game is a lot like one of my favorite games of all time, Crimson Land. I hope you will work to improve it some, I'll keep an eye out just in case.
