Mmmm.. i feel like a fish out of the water here, with all this good comments, but honestly i really didn't enjoy my experience, so far, with this game. I admit i havent finished it. I dropped it quite early. Maybe i'll try it again later, i don't know.
To me, pros: The models are very cute, the concept of the game is a bit fresher then your standard VN, a lot of animation.
Cons: I honestly found the gameplay painfully boring. Click on a location. Passively watch a scene. Do a shuffle 15 minigame. See some more scene. Repeat. The dialogs are plain terrible. They feel stereotyped and lazily written. There is no story as far as i went. Just a guy, the MC, who stumble on hot girls from his school and flirt with them, for their universal, unconditioned, bliss. And go on like this for, like, forever. Dirty scene look kinda weird although the girls are cute. When in subjective i felt o could went into motion sickness.
I swear i dozed off a few times. Ok, i've been working 7/7 for a couple of months now, and i'm rather exausted but i feel like i would have dozed anyway.
