Really been enjoying this game so far, and I enjoy how much different content there is.
However, can we expect to see nsfw content with other side characters? Personally, I'd most be looking forwards to August or Alice, because tomboys are amazing.
There are plans to have sexual content with those characters down the line. It's just going to take a bit to get to them as we're focusing on the main character routes at the moment.
I am glad to hear that you're enjoying what is there so far though! Makes working on the game all the more worth it!
