Just loaded the game and this looks like it's gonna be a winner. Everything is working fine on Win10, no GPU, and only 4MB RAM.
I do have a couple of suggestions tho --
My only issue with the UI is the control of the girls! Having to move the mouse around to control the action is really awkward, detracts from the game, and it's VERY choppy. In a 'perfect' world, a slider to control animation speed would replace this. 2 sliders could even be used. L/R to control speed, and Up/Dn to control penetration depth. Some of the girl's faces are PRICELESS when she gets 'filled up' lol! The female's excitement level could show in a bar that fills as the scene progresses. The stamina is almost impossible to read in several of the scenes anyway.
It also seems a little awkward that the girls stand up between positions. When the next position is triggered, just leave the animation running until the next option is clicked. It's a game - let us play with the girls W/O wearing out the mouse! They're all really hot BTW.
This is a unique idea for a game, and playing it is pretty enjoyable. By going to the bar and working a part-time job I can now make around $1000 in 4 tries. Making it rain at the strip club is a bit of a grind tho - maybe give the option of how much money to spend and award increased stats accordingly.
I'm looking forward to your updates dude! Nicely done so far.
