Nice game.
It's certainly different. It's educational (in a way, but anyone that visits this site should know simple math), and it makes you think highly. It's not exactly a simple game when you get to the later levels, which I like. It may not astound you with flashy graphics and whatnot, but it's a simple game that I like a lot.
Very original
At first I wasn't so sure about this game. However, once I got into playing it I found it's actually a really original and fun puzzle game. Good work.
Good stuff
Would be better with sounds... but otherwise seems pretty good.
Quite good
Very well done game. Good concept, nice gameplay and I like how you kept adding on the concept as not to confuse people. Keep up the good work!
Good (:
Really cool idea...
Could of had some sound FX when you pressed the circles
Also, some relaxing music in the background?
Good work
