Let's talk... I'm not a games expert or a value critic, but I can tell you that this game doesn't deliver as much as it promises EVEN though it's a "beta" or "demo". I, like many others here in the comments, was interested by the game's proposal, being different from other +18 games that always had the same gameplay, something 2D of questions and answers, hits and misses, go back to Save-Point and do it again if you missed. In this game the proposal is much more interesting, going out to explore an island with monster girls and taking pictures of them and so on... but the game takes a VERY long time and is VERY boring and tedious.
I'm not going to lie here, I paid $13 to explore the game and "enjoy the moment" as you know, and the gameplay, the graphics, the physics and worst of all, THE SCENES, are all very disappointing or less interesting than I expected them to be. So far I've only seen ONE scene, and I admit it's good, but the HARDNESS of getting those scenes, the TIME it takes to get the scenes, and the TIME I need to spend out of my day just to "relieve" myself are not worth the $13 I paid for this game.
So let's get to the final considerations with notes:
Graphics - 6/10
Environment - 6/10
Gameplay - 5/10
Progression - 3/10
Sound & music - 6/10
Character voices - 5/10
Character animations - 4/10
Bugs - MANY
My interest in getting more scenes - 1/10
Conclusion: The game's premise is more interesting and even eye-catching, but it's not what an adult game fan would want to see, and it's certainly not worth the price.
Final score - 3/10
