hi there. Atm there is no need to buy. Donation is just optional. As this is very very early in this game it's really just putting things in place and being able to to interact a bit with the characters(will be working on making the characters seem more alive(so to speak) with updates coming. In the next update coming up shortly I'll be adding two more girls and guys versions but I am currently working on a big update for after that. Currently a portal room and a BDSM room is available but in the big update I'll be adding more rooms such as hospital, masters chair, laboratory(experiment room etc. I have so many plans for this game ( way to many to list here) that include making it so you can customise the character live,for example make them chubby or really muscle mad (done a chubby version and muscle version for a character already as a preset for the next update). In regards to fetish, there are plans to do as many fetish as possible. For example vore, giantess, public, foot fetish, tickle fetish,. you name it. In general I'm trying to make this one of the best adult games out there, that gives the player the freedom to do what ever they are into but at this time it's putting the bare bones together. I've put together a discord for patreon supporters so that they can tell me what they would like in the game and I will do my best to facilitate but atm there's already so many plans for different fetish etc. (Long talk over, sorry passionate about making this game and could talk forever about the plans I got for it haha)
