Gave it a run through to see what it had to it and any bugs to post about.
Bug#1: the calories are not processed after you go the bed making it so you cannot gain any weight and can only lose weight I thought it was a calories issue but after trying to get as many as i could nothing changed.
Bug#2: There is an error once you become obese and wake up (I tested this with my own rpgmaker program) the game throws an error your way saying it cannot find the picture gf_obese_sleeping so it locks you there unless you can put a picture to replace it.
Bug#3: When you use the OnlyFats interaction on the computer and finish the work you receive money and fullness but it does not lower hunger or give calories.
So far those were the only three errors I could find but all the other intractables add stats to you fill your fullness and lower hunger all of those function work when use. I don't know what is planned but the framework is here and functional except for the components mentioned above.
