This may be difficult to try but for a couple thoughts and ideas that could be interesting to think of:
-When multiple npc characters are around each other in the wilds adds the chance for a three way or specialty more?
-if the thought of adding multiplayer comes to mind if possible have character interactions with each other and npc's?
-bigger burly characters if not somewhat feral (in horniness) on the hunt capable of tackling you for some fun?
-Boots with boost of jump mobility or shirt with little wings giving a lite double jump?
-Little water sources in areas to maybe be able to put yourself out from fire spells?
-Obviously more species types to customize with? (mouse, equines, raptor, snake, sergal, avian, bovines, hyena as just a couple options etc)
-Maybe the option to seduce npc's from the wild enough that you can have them follow you home to keep at your place if you like how they look and all and want to keep them around more? Obviously character living space limit to maybe 2 or 3 depending on your generosity ;3.
-Maybe the option to have the ability to remove getting your butt beaten up by anyone while you are "having fun" with a character in the wilds?
But as i may think of many random thoughts and ideas that i would love to help and share with you i personally love everything that you have done up to the current point so far where i already spent over an hour or 2 in character customization alone because of the detail choices being so amazing and being able to add on top of what's there to mix and match. Gameplay is very nice and smooth to boot. Though may hope for controller option in future maybe? the town npc's have the perfect emotions for their emotions and attitude etc. kind of guessed the town whore before speaking to them lmao. other than that i really look forward to what you make of your beautiful work in the future and can't wait. <3
