Not too bad of a breast expansion idle clicker game, though it's pretty clunky due to the way RPG Maker handles "character" (your cursor) movement and the click mechanics.

Also the game's pretty grindy, which makes the game a bit dull to play after a bit, and the gameplay's not really complex enough to make you really "want" to play it. Art's nice though, but it comes with that downside a lot of these kinds of "unlock girls for porn" games have where there's not really any way to know what a given scene is like until you've spent the time to unlock it.
It's probably fine in THIS game, but man, some games are like "oh you spent an hour working on unlocking this girl? Too bad, it's a sloppy anal scene!"

EDIT: Forgot to mention that half the characters are behind a paywall that isn't obvious until you try to play them, and that all but the first character have added gimmicks to the gameplay that are there to slow you down further and add to the grind, which sucks.
