This game was pretty hard to get into. I played the web version. When you're put in that room with a million tutorials and the dreaded perk room, it's very tempting to go straight into the game.
OK, let's pick easy mode, then! I'll learn the mechanics while playing! Well, it turns out easy mode is pretty hard. Try again and die a few more times.
Let's read some tutorials! OK, so you have to hold A to aim while attacking, unless you're in claw mode, in which case... you can walk while attacking... Why are the controls so complex? That's asking a lot of me to remember all that.
I read it all one more time to make sure I got it. Nope, I shouldn't have to read about special abilities yet, I don't have any of those, right? Let's just try again, this time I'll pick the slow mode. I manage to shoot an enemy twice. Proud of my achievement, I quickly notice it hasn't died yet. I run around for a while, trying to use the scratch ability and managing to fire two more shots, but so far no enemy has fallen. The enemies surround me from all sides, and defeat me in an instant.
I think the problem here is the amount of depth in the game, which you're exposed to from the very start, without training wheels. I think if you simplified the controls to start with, hid away the perk room and the character customization, and introduced one concept at a time in a series of linear training missions (with waaaay weaker enemies), then even I could learn to play this game. Right now I can't do it. It's like asking a cat to play badminton.
