That's probably why - it's a fighting game - too much violence. My game is violence-free. There is no 2-player mode in my game - I have no way to test it as no one around me is even interested in it (they're not gamers or, in the case of my sister, not interested in the genre). Multiplayer isn't my thing either.

I've had intentions on improving it since something like version 2.1 was around and since 2.3 started for sure.
