Maybe instead of making it free, make a demo that's free to play that only has the first girl or two so people can tell whether they want to buy it or not.
Hi Nickel68,
That' a great idea! I am currently working through the design for enabling a demo.
The game was never designed to be partially consumed so it might take some fiddling to make a demo work.
I talk a bit about it here
Kind regards,iLEWD
