Just from looking at this, it genuinely looks like it could be a pretty good successor to GrowthRPG by DigitalFurBelow, if you ever decide to go the route of "game mechanics that allow you to change physical attributes/their size outside of character creation" (whether temporarily or permanently)
That aside I think I'll wait until it's more feature-complete before buying it, as judging from the patch notes there's a lot of important basic stuff still being added and developed.
