Terrible. Your cursor is UNDER the enemies for one thing, and also I found myself unable to kill more than 2 thugs before I died. Unsure what you are teaching here, but I like the attempt. I hate reviewing "works in progress" because that always felt like a cop-out to me. it suggests that I shouldn't be too critical because this isn't done yet. If that were the case, I wouldn't upload %5 of a game and expect people to not hurt my feelings.
Again, I like your ideas, I just don't like this game. Would have been more helpful as a tutorial if it broke down the features and explained their code while you were playing.
