Happy New Year!
During the holidays I had some ideas/questions of the future development:
1) What do you think of adding symbiotes to the story?
2) Do you intend to add a muscle drain/milk scene: e.g. a muscle thief on Hedon, who tricks the buff guys to top him and drain their size after they cum in him. Alternatively there could be a very thin and frail guy (space villain), who drains the best assets of different creatures while top or bottom them (muscle from Hedon, virility from Taun, demonic powers from The Scar, ...) incl. the main character. After each draining scene the villain will become stronger, dominant,...
For a milk scene: muscle breast lactation with the help of the chemicals on Hedon, every guy who sucks the muscle milk from the main character while he bottoms gets bigger.
3) Will there be an option to individualize (species, height, muscle mass, ...) one of the companions? May be combined with a shapeshifter slime (like the tentacles on Taun).
4) Will there be a way to sexually interact with the inhabitats of Sciurus Metallicum after the testing?
5) The temple and cult of Taun (Gnolls): Could they summon an angel/demon with their cult at the vulpix statue with the main as an offering (existing bad end there)?
6) Space ship story: After the size accident with Miles on the ship: Miles could beginn inventing a growth potion for the main character that he can top him. But Kuno/mouse/etc. drinks the potion. He will grow tremendously. (...) Can be reversed with a counter potion.
These are just minor opinions and ideas from my point. I don't want to push anything, there are just small impulses. Maybe they contribute a bit to your creativity.
Have a nice, good and creative year. Stay healthy! (If I wrote to much much: I'm sorry.)
