I like where this game is headed. I think the damage speed is set a bit high because I seem to be moving pretty fast and still taking damage. It was better with a controller than the keyboard for sure. I like the menu and the presentation and the sound. If I had to add one thing to this, it would be better input. Its begging for a mouse drag control for non-controller players.
There is a lot you could do with this though. Ideas to up the fun factor flowed out of my head while I was playing it. Its a solid concept and a great start!
