Those are all the endings in the game as of now, the next update will have a pretty crazy ending as well.
Ramoray will play a bigger role in the future for sure. I'll leave it up to the players on Discord/Patreon on what the players want to be added to the game. A bodybuilder girl probably not, but a very fit/slightly muscular girl would very much be possible.
Your idea about make someone to help him stay with a human mind is great. I'm working on that as we speak.
In the next updates light/dark choices will play a bigger role.
This game is only going to get better. It only came out 3 months ago and there's already so much stuff happening. I'm very excited for the future.
P.s,
It think "Niche" is actually a French word. (niche market) "of interest or appeal only to a small number of people."
