I'm going to be honest i mostly play NSFW cuz they are somewhat fun to see, but I'm really into this game and the puzzles and the art is just a very nice extra, like even if somewhat repetitive are just fun and I'm really enjoying the game, the thing they give you to change the genders of the characters is a really nice thing for people like me that are into almost everything lol, (i think i overexplained a little).
it's a very nice game and i have resolved 300+ puzzles apparently
