Not sure if its been asked about or mentioned but do you have any plans for the player to react to their weight, I think it would be interesting to have options when creating your character to choose how they react to their own weight gain, could even tie into the corruption sytem you have mentioned where the feeder characters could "corrupt" your player character.
Thanks for suggesting this. I don't think anyone has mentioned this idea previously & it isn't something I'd considered!
I created the current system from the perspective of 'you, the player, know what you like and how you would feel about the weight gain of your own character'. But as you don't experience the actual sensations of what it is like to get fatter, telling you how it makes you feel would work really well. I like your idea of the feeders being able to mirror the player with the corruption system, too.
