Fast, fun, but too hard to enjoy.
I may catch a bit of flak from a hardcore gamer making this small critique, but I really fill the difficulty of this game makes it harder to enjoy then it should be. I mean, it's fast paced, interesting, I like the characters, it's got guns, and nice music, pretty much everything a game needs, but damn, I don't even think I could get my little cousin to play this with me cause he barely make it through the first level(He's not all that good at game but I try to get him to try different things). Compared to Hero Seige, the ony other rouge like game I've played, you barely have a chance to even get through the first level if you're not used to playing games of this nature, nor can you if you're not ditermined to get better at it. If anything, I would suggest adding a difficulty setting, and adding a bit more health and health kits, or at least not taking 2 or more HP away per damage taken. Not to mention due to low numbers in exp, I can't even take what little advantages I get from the mutations in a good amount of time, usually having to wait till after level 2.
This is really all I got to say. This is good for a challenge but it gets pretty old when I have to play the first stage over and over again, some of them have 3 of 4 scorpions turning the game into a bullet hell, not to meniton the desert boss.
I do want to ask though, how long is this game?
