My gameplay suggestions:
- Size plays a disproportionately important role more like level than like a stat, so it should not be a stat unto itself; it should increase proportionately to the total of all other stats.
- Scaling should work by typing in an integer value, locking the character's visual appearance as if the relevant stat or Size were that number.
- Ego's numeric value should be visible so that the player has a frame of reference for the above change to the Scaling UI.
- Scaling should be available for the partner character as well (Mad Chimera's tits became eldritch abominations after the 700s or so.)
- The player should be able to toggle Pain and Gain on and off, since it is required for all other Muscle skills but also endangers your armor.
