I saw this game on steam the other day, thought I'd take a look at it.
It's pretty mediocre at best, annoying at worst. Games like this remind me of a variety of old flash games from the mid 2000s where they really make you work for that fap material for quite honestly no good reason.
I think the setup is fine, and I'm sure you could make a functional game with some basic strategy to it (In fact i am almost certain outside of Orgasm Girl and Orgasm Girl 2 there is at least a handful of games that have had some sort of massage game in them better than this)
But fuck me man, why the fucking timing game with a circle? I never feel like I have an intuitive understanding of the circles speed of filling. That doesn't excuse the other "wiggle the mouse" and "test your mouse flicks" games that are here, though I can see the one for when you're ACTUALLY doing any sex related activities having some decent gameplay.
I know it might seem stupid to complain about gameplay, but it's there, it can be done to help sell what's going on (I've seen porn games do this), and I think I'd have rather the nuisance be the feeling that I could have just downloaded the CG set for this game and gotten equal enjoyment from that or something.
I'm still kind of trying to play through the 1.1.5 on the front page atm because I do like the setup though, but boy does the gameplay make me dwell on it enough to complain at length like this.
