I've only just started and this game is already significantly better than a lot out there. The cheeky intro is really hecking adorable, and I can't tell you how nice it is to have a safe key. So many times I wanna try a situation out in a game like this, but then the only way to back out is to close the game.
If this is anything like the stretch game, or if the character of its own opening continues even, this is gonna be a great game (and not just for the lewd stuff: I love a cutesy ending).
