The tennis minigame is broken. I don't mean buggy, I mean it's like someone played Pong once in 1987 and thought yeah, I can code that, but with tits. You're supposed to hit a ball past a pixelated girl who barely moves, and if you win, her clothes fall off. If you lose, same thing basically. It's not a challenge, it's a formality. The whole thing feels like a formality, honestly. Like the dev had to put a game in their game so they grabbed the first tutorial they found and slapped some hentai on it.
The trainer character has these glasses that are thicker than the plot, and he's supposed to be coaching two students. One's got the classic big tits Japanese student look, the other is... also there. They're all horny in that way where nobody even pretends to have normal thoughts. You're just clicking Next, Next, Next through dialogue that reads like it was translated by someone who learned English exclusively from porn subtitles. The tennis scenes interrupt the clicking every few minutes, and you play this weird ping-pong thing that controls like you're dragging your mouse through mud. Sometimes the ball just phases through the paddle. I wish the minigame was harder or at least more interesting, but it's not and it won't be.
I kept playing because I wanted to see if the sex scenes got weirder, and they do. There's one where the glasses stay on the whole time and it's framed like a training exercise, which is the most self-aware the game ever gets. The art is inconsistent, some CGs look almost good and others look like they were drawn during a bumpy bus ride. I don't know why I expected anything different. The whole thing is like a fever dream you'd have after falling asleep watching anime at 4 in the morning, except you're awake and you chose this. The Award for Most Unnecessary Tennis Integration goes to this game, no contest. I'd say I want my time back but I knew what I was clicking.
