People have made all kinds of complaints about Gluttony being confusing or imbalance or what not but I want to make a very specific one, the current implementation is UN FUN because it has so much time pressure when in Gluttony. Your trying to click the right foods while the acculturated humor bars are shrinking and its got huge potential for you to get veerrrrrry close and then run out of food meaning the whole thing is a waste. This aspect needs to be changed, I would recommend the follow simple changes.
*Humor bars do not decline during Gluttony and they are retained when going in and out of gluttony mode.
*Invariance penalty acts to subtract from all humor (food that would add 5/4/2/1 with Invariance of 2 only gives 3/2/0/0)
*An additional 'Stuffed' penalty also subtracts (cumulative with Invariance) but it rises with each item eaten in proportion to the items current eating time.
*Interface shows the modified humor gain of an item you might want to eat after Invariance, Stuffed or any other modifiers are applied.
This would basically give us the same overall pattern of diversity being better, small 'fast-foods' being better and a quasi cap as your unable to raise stats beyond a certain point given a certain level and diversity of foods. But their is no longer the frantic clicking or the chance for massive food waste because you couldn't judge how fast the crazy set of bars are moving. This will also reduce overall confusion with the system because people will have time to learn how it works and can eat strategically just as we often strategically study.
P.S. Bring back the Tables from H&H (I tire of eating from a crate) along with the Symbel system but with a wider set of effects, items could offset Invariance and Stuffed penalties (flat reductions, percentile reductions, slower growth etc etc) as well as give multipliers on each Humor separately so you could make specific 'place settings' for different eating goals.
