A rather unusual game, this is a puzzle game where you use various math operators to construct a correct equation within the time limit. Although Fuga Soft games generally don't contain adult content, the addition of a partially naked girl at the beginning leaves open the possibility this one may have adult content. I didn't play far enough to find out.
