I have just started building in Linux, so expect that in the next public build. There is a web version on Newgrounds.
Newgrounds adult games are kept separate, you have to first search 'adult', or 'porn', or 'nsfw'. Then it will ask you if you are looking for adult content and redirect you to the NSFW side of newgrounds. As for finding it in newgrounds https://www.newgrounds.com/portal/view/763159
