This is a good way to kill ten minutes. I liked how you could change the CPU's skill level. I started losing to the enemy at fifty percent, and I had to quit out of frustration. The blue circles were a good addition to the game. Granted, they annoyed the crap out of me, but it added to your strategy. Is there a certain game collection you'd like this to be added to? Overall, it was a simple, yet puzzling game. Keep up the great work!
