10/10. Simple. Every aspect of this game is perfect, and I wouldn't change a thing. Sure, everyone tells there's always room for improvement, but I can't possibly imagine what that would be.
+ Render quality. As you probably would have seen in the preview pics, the renders are really good.
+ Models are gorgeous. Each and every one of them.
+ Every character has a personality trait. Each of them are different and this provides variety.
+ Branching. It's still in early stages but there's already a lot of branching and you choices actually do matter.
+ Animations. Fluid and crisp animations. Don't worry they aren't image loops.
+ Interesting plot.
+ Dialogues and H-scenes and done very well. Not many games show you the foreplay and undressing. It's like one minute you're kissing fully clothed and the next minute both of you are naked. But here, there's proper foreplay before the sex. I don't about you, but that's a major turn-on for me
Sandbox part of the game is taken out after a few minutes into the game, so don't worry about it. Download it, it's surely worthy of your time. Pledge material.
I wish all the best to the dev and hope he gets all the support for this game. He deserves it.
