Mainly more growth stages and dialogue for npcs. 

Okay, wow there’s a lot of variance here on thoughts concerning this game lol.  I do want to say I am enjoying this game, but I do agree with many folks here, that the game’s XP vs enemy difficulty is _WAY_ out of whack.  It also doesn’t help the growth types have skills locked to them without being told about it.  I do want to say I’d appreciate if there was also an AE or hourglass growth type.  (or being able to mix and match a bit.  I _LOVE_ bottom heavy FBBs and there isn’t a lot of representation).  Another thing I’d like to ask is if there has been any thoughts on putting any furry taur species in the game?  (Sort of like a more ‘furry’ Arachne or any other species with a non-biped lower body)

I’m making a side save at work seeing how the 2 growth types I haven’t seen yet skills work (breast & WG) seeing how it goes without the stun attack from muscle goes.  But more importantly than that I didn’t even notice that the game gives split XP.  This makes it MUCH harder to have a full squad rather than just boosting a single person.
I’m finding Luna Nightshade an absolute MENACE to get through.  Especially since she’s immune to stun.  It doesn’t help that she’s essentially a blockade to overcome to get to the 2^nd portion of the currently completed game.  This is on top of the rather odd difficulty scaling between the beach area and the Nightshade clan zone.  Enemy levels jump from around 30 to an average of 55.  Even if you factor in the WT the enemies there (unless the homage drops something major, haven’t killed 6 of them yet) don’t seem to drop anything of note.
Does NOT help there seems to be no way to gain better defense in the game.  You are stuck at Bronze armor as far as I can tell (the wiki does not even detail one steel is open if you can make steel armor.)  

Also that you cannot really ‘craft’ weapon upgrades to help overcome Luna either.  You are reliant on rare drops from enemies.  The best I’ve found so far being the spiked mace which gives atk equal to 5% of max hp.  There’s a verdant greatsword dropped by the forest guardians, but even after over a dozen I’ve yet to have a single one drop at their 5% drop rate.

That and at current the 2^nd foraging location, woodcutting, crafting, and cooking systems feel completely unutilized to their full potential at this time.  These just don’t seem to have any weight behind them yet.  Woodcutting only gives Sturdy lumber and apples as far as I could tell which is kind of pointless.

Dreck I probably have more gripes I didn’t get to in this either just don't have the time right now.
