To be honest, the game is pretty nice. One improvement would be too add more achievements. Achievements are something to strive for, people will play more if they have some more goals to reach. Another improvement would be making it more difficult to obtain all the girls. Once again it would make people play for longer racking up playtime. I like the idea of the game but with these improvements I would definitely play more.

I bought this thinking it was one of those "seems innocent but is actually creepy" games, but instead it's one of those "answer math questions as fast as possible and the girls show their chest and feet" games. Can't tell if I'm disappointed or not.

This game is about doing math really fast. My big bro tried it too, but he got distracted and I beat him. Now I’m smarter. I recommend it!

Very cute game. Turns out I'm garbage at math though.

I like the idea of the game but for my understanding, you shouldn't be able to unlock all of the girls (basically all of the possible levels) in a matter of a mere ten minutes. We are on the right page if you like some decently drawn pictures of girls in suggestive poses as a reward for some basic math but what we have here right now content-wise is really nothing to write home about, not even for one buck. I want to end this with a positive note tho that if you plan to complete the album with all the stickers, you might get a few hours in. Perhaps if you play this only from time to time, the game's value will become more apparent. It did run without issues on Debian 12 Bookworm for those who need that information. Thanks for reading and have a nice day!

If you solve maths equations fast and correctly, you get to see bobs and feet.
