A bit hard
The thing about this game that was difficult was the gameplay. The tutorial seemed a bit confusing. I know that I killed all my enemies, but I think I accidentally killed one of my own guys. At least I had fun watching those guys get shot over and over. I find it humorous how a rifle would be able to miss at such close range as the person does not seem to move at all. There could have been some more detail in the background.
I liked how you put in a whole lot of songs for this game. It shows that you wanted to create a specific mood for each thing. Besides the background, the graphics are actually quite nice. It's especially cool to see the players/characters interact across the board and attack each other like that. It seems a bit hard to use the knife, though.
