This was just an okay game. I couldn't find that much that was appealing about it. It seemed like you just went after the same enemies over and over. I will say that I liked how it got one more on each level. I was afraid at first that it would multiply by two every level. The graphics aren't that good.
I also like how the tiles disappear. That really does make it harder. Going for the center is always a good strategy. I can see why this isn't that popular. It's just nothing noteworthy.
