my honest opinion, literally wtf did I just play and what other direction do you think should I drag the character while having sex it's just back and forward (in the given situation)
it's common sense
"it's just back and forward" - not really my dude - there are some animations where you have to drag the characters up/down. And it's not just about the direction - the speed changes, there are different kinds of arrows, etc.
I should also say this is a free game I made out of boredom that literally takes 3 minutes do finish. Don't expect GOTY award winning material here.
