It could be better
I think it could have been better if you had guys comming from 4 directions so that you had to move and not just stay at the top being able to hit everyone, another thing that would make it better would be if (and i know i might be flamed for this) but, add a rpg kinda element to it so that you could have fat drunks that woulndt go down after one hit or you could have tri shoots, or rapid fire either powerups or skills, I know there was the motatove(spelling) thing but that was only useful when there was 7 standing around the keg. It was prety good for what it was but i hope that you could inprove it
