I can't keep up, it's a little hard to understand

I have already played it for 30 minutes and I still can't understand the tactics of this game. It's hard to play and it's even hard to control. I think it's not a game for me. I keep on dying LOL, I'm running out of patience here. Can somebody show me how this game works? I've read the descriptions and it says "It's the hardest game ever made". What?
