Backed this a little while ago to check out the slut story/ending.
First I picked the wrong tier, so had to fork over more money, then the multiple choice minefield of the main story had me pulling up the walkthrough faster than I have in a long time.
The slut story was very short, but very good. Sadly I can't really say the same for the rest of the game. You have to be so cautious with the choices you make in the first half of the game as game overs are really easy to hit, and after a lot of frustration I gave up and resorted to the walkthrough, which I really didn't want to do, spoiling the story and all.
It's hard to decide on the number of stars for a review. On the one hand I don't regret backing the game and playing the slut path, on the other hand I didn't enjoy much of the rest of the game, but it's also my personal preference for games that focus on developing (or corrupting, my preference) one character instead of many.
I guess if you don't mind paying a premium for a slut/corruption game that only lasts for half an hour, I think you'll be happy with what you get, I was. And again, the art is way better than most games. But the rest of the game is a bit all over the place, side characters and quests that I'd like to just go away, unforgiving multiple choices that end the game often, clunky save game system.
I think if this team just did a basic, straightforward corruption of one character scenario for their next game, they could do really well. I hope they do.
