Played a little bit. I'm not your target audience though, since I'm not a fan of the genre, so I won't really talk about the core gameplay.
Some critiques or things to watch out for:
- Against the blue haired succubus I got Lust to 0, and every subsequent lust attack had no effect. Could that be a bug perhaps?
- I didn't read everything, but grammar is off at some places (particular example, the blue haired Succubus's double slap)
- Why are the attack icons different? Every other color has only one icon. At first I though you could only match attack gems with the same icon.
- You might know this, but just in case, difficulty wise, I beat two girls just by brainlessly picking the largest chain I could find.
As things I liked, the girls are hot. I was sad to find there weren't any h-scenes, but I guess that was obvious, lol.
