I don't think this game works very well with a laptop. I was not able to move and attack at the same time. I know there are games like this. I'm impressed at the high number of songs that were used in this. Looks like your second one did a lot better. The graphics were okay, I guess.
I didn't like how it was pretty difficult from how I played it. This aerial shot is fine, though. Killing again and again is a nice idea too. It seems a bit too complicated for its rather simple premise. I would not recommend this.
