Heya:) glad you're enjoying stuff. So with the Revamp, I didn't plan to have any extra NSFW scenes; however, I didn't make a lot of plans with the original game and it sorta just wrote itself. So the short answer is they're not planned but that's always possible. There are a ton of changes in the Revamp visually-- some of which include NSFW content-- either adding more in some scenes or using new tricks to obscure stuff more artistically. Almost every scene in the game has expanded CGs now so that could easily translate into more NSFW images to make the same scene. The Revamp is planned to follow the same story tho-- it's just waaaaay better quality in every way.
So in terms of another game: i haven't officially announced anything. Truth is that I'm terrible at multi tasking and i dont do well splitting my attention. When you're doing most of this solo, there's a lot of jobs to do already-- trying to take on another project while doing all the work that Str8 requires, is just not something I naturally excel at. The work with Str8 will gradually get easier with each Revamp update. I'm through the roughest parts of the writing now so that's getting easier and the end of the game will just need some image touch-ups so that should go super quick. That extra time should help me plan any future things. I've also began the process of learning more animation and tyring to techniques in Str8 that could apply to future projects on purpose. I will say I have a secret folder on my computer and another notepad on my phone tho with some things I'm tossing around :p
