It's too early for me to leave a proper review, but what is for sure is that it's interesting. The redraw of the sprites made the game much prettier ❤
As for NSFW or not, I have an idea. For example, a scene like "whoops, I caught my love interest in the shower with his cheeks out" or something like that. I think you don't need to write something particularly long for this, it can have a comedic effect, doesn't require any particularly inappropriate art and this doesn't mean that Felix will have sex with them. I think this will calm some people down XD
Nsfw themes for the datable characters can make it more entertaining but I feel most people will find what I like to call “wholesome nsfw” more fun like the example the above mate gave of felix finding his love interest naked in the shower, or romantic cuddles could also be a part of wholesome nsfw, biting and certain sounds yknow make it feel alive by adding passion. I know that sort of stuff if drawn can make it easily 18+ but when felix describes it holding his lover in his arms and feeling his heart beat getting faster as he is puuring and enjoying the moment of pure love will surely make it satisfying to alot of people even the pure horn dogs
