Firstly just wanted to say that this game for just being a demo, is incredibly solid and has more content than some games that have been out for while and have had multiple updates.
Unfortunately I really can't provide help for coding or asset making, on a side note about assets please keep the flatten cube scale that caught me out the first time I played the game, and it got a laugh out of me ngl.
Okay time for a bunch of questions and slight potential bug fixes?
I've had a look about the files and messed about with some of the gain rates for a few characters like the witches. Their stage 1 rate is 0.3 then stage 2 is 1.3 and stage 3 is 1.8. just curious its your game you design it how you want, I increased stage 1 to 0.8 just to be more aligned rate increase per stage.
Along with this I slightly increased Jenny's and Carrie's rate and slightly lowered Maggie's rate for their event.
Also Rachels images aren't appearing when I visit her after stage 1 but Bailey scene during the visit seems to repeat twice no errors are popping up I'm playing version 0.1.02 if that helps.
Just few questions for future updates, could there be an option for disabling the burp noise to be considered? Its fine if it isn't I have the sound volume turned down to act as a mute. Nothing against the burp noise its just not my thing.
Also the planned feature of male weight gain and mutual gain would that be optional or not? like I said before nothing against it just not my thing, also its your game you design it how you want.
Also congrats on getting the images files reduced. It'll go a long way for keeping the file size of the game manageable, I don't know but maybe look into reducing the video files sizes as well. It would help the game's file size manageable going into the future.
But that's enough from myself. Really I been haven't this impressed from playing a new game like this since playing Fattening Career and Project realism.
TLDR: Game is really good please keep up the good work, really looking forward to future updates.
