This was actually a really interesting version of this type of game. I enjoyed playing it quite a bit. I think that the animation is a little choppy and that the graphics could be improved, but it kind of had a style within it's own. An improvement in quality of the graphics would make my score go up for sure.
The gameplay was ok, but there really wasn't much of a challenge in my opinion. This could have used a lot more upgrades and depth. It was very basic and didn't hold much replay value at all.
