Sakura Magical Girls Review (dolomynum)
It's a goofy and light-hearted VN (or AVN, if you install the adult patch - check the forums). The protagonist works as a cleaner at a beach resort. At the beginning, he goes on lengthily about how he hates his job as a cleaner, but he has no choice as he must pay back a loan. After even the most challenged people have hopefully understood that he hates his job as a cleaner, he starts cleaning. While at it, he is attacked by some hentai monsters such as a squishy blob of slime and a tentacled plant. He is rescued by cute magical girls in harlequin costumes, who annihilate the slime/plant, then invite him to join them on their adventures. Said adventures consist of various events, for instance doing wizardry training, going on forest walks or leisure cruises, or the girls getting stuffed by the slime monster (the plant is not seen again btw). Each of the girls have a crush on the guy and they keep flirting with him, but he is oblivious and just stands around, and goes on about hating his job as a cleaner. The game ends with a cliffhanger, however, no sequel has been released.
