here's a thought, you know in the Goblin Tower on the second floor where you can train with the dummies, maybe make the training as an "exercise" so that it would deduct a point or two to the gluttony score. it would require 20 VP and 2 game time hour/minute. you could make it more taxing to "exercise" as a form of consequence from eating "unhealthy", or in my case, spamming baked potatoes. haha. just a thought.
on a side note, game is amazing by the way, even in its alpha stage. and to think you're developing this (I assume) on your own. more power to you.
