Don't worry, I do appreciate feedback a lot! The best parts of development were when I got to watch people play it and voice their opinions, and the game has become better for it. Reading the comments has also been very nice, and it has motivated me to fix things that I wouldn't have fixed otherwise.
As for the goddess requiring too much nutrition, you can change the required nutrition by editing the savefile data (%localappdata%/gain_factory/game_data_.ini). You just find the variable "goddess_nutrition_goal" under the save that you're playing on, and set it to something smaller. For the hardmode goddess, you can also alter the loss rate for the goddess by changing the value for the variable "goddess_loss_rate". Most things are stored locally in the savefile, so in theory, you can also change things like cowgirl appearances, though the savefile isn't optimized for human interaction. The saves are in json format, but all the " are replaced with <.
