Hey I like your game, very nice graphics with simple and straightforward gameplay. I think the UI elements are too close to the edge, adding a small padding here would be great. I don't quite understand the game win and lose messages. When I win, I get "Math has taken over the Earth" and "The Math god has saved the earth" when I lose. Maybe I was not meant to defeat the Math god? haha. I also found a bug that I can click on the right answer multiple times very fast so I get multiple points for it =D. Otherwise, great work done in a short amount of time!
