There is an option to download it for mobile as a .apk file. Not sure if it shows up as a mobile game on itch. I didn't see an option in the upload settings for that.
Also I am currently working on expanding Cathryns playthrough. In the first update there won't be a new character yet but a chapter 02 on her story.
As for your ideas, all those story tropes will be touched on using various characters. Thank you for the feedback! :)
