Worth checking out- these guys used to work with the creator of the astonishingly brilliant new PC game Circa Infinity. This one is also about circles and color matching. Having the color wheel spin as the difficulty increases is a fantastic idea, preventing motor memory from taking the place over higher level puzzle solving. That alone would make this game deserve 5 stars if it wasn't for a very basic flaw: the first minute or two of gameplay is so easy that it makes replays a chore. The difficulty should ramp up MUCH more quickly! Or better yet, give more points for going faster- the countdown clock at the beginning gives you so much time that the only incentive for going fast and risking a mistake is boredom- that should never be an incentive for taking risks in a game. And the cost of risk is too high- mistakes on a countdown-based should take time off the clock, not one-hit kill you. Fixing these simple things would take almost no additional programming and would turn this game from a neat idea to something genuinely fun and mentally stimulating. I look forward to v2.0 (hopefully)!
