The controls are somewhat unintuitive, you should either add keypad support or a note that says to use the hotkeys. Other than that though it's great for what it is.
Easy, relaxing game
More or less just times how quickly one can figure out math for more hentai~
Really great game! I never saw a game like this before so this is new to me! Its got great potential to it! I made it to level 20 no problem, then you started doing 3 number addition which is hard to do in 3 seconds! so at least bump up the timer at level 20!
it helps with math, im surprised i got to 12
This game is aimed toward adults, so that every one of us has learned addition and substraction at least 10 years ago. Now, we just find it boring.
