Played it. Everybody is all about the crap.. but holy shit, the grind! Its pretty much just unlocking options and you have to grind for it. A lot. Its like cookie clicker. You have to wait to click options again tho, as they go on a cooldown... and thats it. You click endlessly so you could grind more to unlock more options. Options like whether you want to see the tongue or not. Have a nose hook on her or not. Have a shower or not.
There are dozens such option, various girls in the exact same pose. But all you do is essentially keep waiting untill you can click the same button again all over again and again and again. Each unlocked option increases the cost to unlock the next one.
I don't know why it worked with cookie clicker for at least a while but here it doesn't really work for me. Might as well watch a picture on the wall while waiting to click on a button. That is basically the game. Instead of a spinning cookie you watch a kneeling woman. 1 base cgi for each and then 90 alteration of said base.
