Synopsis
Train your brain during short breaks!
We’ve erotically enhanced and revised illustrations from our previous CG collections into an erotic Minesweeper puzzle game.
Please try the demo version to see how the illustrations have been made more erotic.
We haven’t made any unnecessary edits, so you can view the full illustration from the main game in the demo version without any compromise.
The main game contains 5 illustrations (+ variations).
