Lost Summer Festival

A spot-the-difference puzzle game featuring the heroine Mizuki. Players navigate through a series of supernatural festival venues, comparing each scene to find differences between "the initial venue" and subsequent locations. The core mechanic is binary: identify if differences exist ("ari") or not ("nashi") at each checkpoint. Touching fox-mask obstacles during navigation triggers a penalty and returns the player to the start. Progressing past the eighth venue results in game completion. The game includes collectible supernatural incidents, customizable heroine appearance (10 hair colors, 8 clothing colors), and sexual scenes triggered by wrong answers or interference with the dancing—totaling 4 erotic scenes. Playtime is approximately 10–60 minutes.
