The first thing that hits you is the art. It's not trying to be some hyper polished visual novel. It's got this rough, almost sketchy quality to the hentai images, like something you'd find tucked away in a forgotten corner of a booru. The girls have these absolutely massive, soft looking tits that spill out of their clothes in ways that defy physics, and the artist clearly spent 90% of their time on the shading of the areolas. The rest of the background is just a gradient. I respect that focus.

So the gimmick is you're solving basic math problems. Addition, subtraction, that kind of thing. You get a problem, a ten second timer, and a text box to type the answer. Get it right, and a piece of clothing vanishes from the girl on screen. Get it wrong, or let the timer run out, and you get a buzzing sound and a reset. It's that simple. I found myself actually getting a little tense when the timer hit three seconds on a "47 + 28" problem. My brain would just freeze, staring at her chest while trying to carry the one. It's a weirdly effective way to make you feel like a complete idiot. The nudity is the reward, but the timer turns it into a panicked scramble. The pictures themselves, once you finally solve enough problems to get her fully nude, are static but detailed. The nipples are huge, the anatomy is exaggerated to a ridiculous degree, and it's all very... direct. No romance, no story, just a math quiz that ends with a naked anime girl.

I wish there was a gallery mode. You unlock the full nude picture and then it's just... gone when you move to the next girl. You have to solve the whole sequence again if you want to see it. That feels like a weird oversight. The whole thing runs in a browser tab, so I had it open next to my actual work, which felt profoundly stupid. It's not a game you play for hours. It's a five minute distraction where you get to see some big titty hentai art by proving you remember your times tables. The math is never harder than middle school level, but the pressure of the timer makes 9x7 feel like advanced calculus. I forgot the answer to 8+5 once. I just sat there and watched the timer hit zero.
