I want to start off by saying I think it's a really fun game so far, It's got great art and great music (especially the part where Jenna time jumps because her suit was removed in the absolute beginning, one of my favourite moments).
One thing I was wondering about, is there a reason why the actual scenes still use Jenna's older design? Personally I'm actually more fond of the simplistic design she had before so I'm not complaining, though I guess the new design does look a bit more professional(?)
As for the new combat system, I obviously don't know whether the Lumber Rats fight was unique or it's because of the Grav Knuckles, but perhaps upping the damage they do would be a good idea? Currently I feel they were way too weak, and it made the battle a bit annoying. The battles in the prologue were fun in all honesty, since they were much more dynamic and fast-paced (especially the fight against Leath was something, I had not expected to have such a hard time with a fight in a non-combat centred game, and yet it wasn't boring or tedious). Maybe the small setting of the bar contributed to it, but I felt it lacked that dynamic action that the prologue had.
Other then that, humour in a game like this is integral! It's an amusing game so far, and that's good because otherwise even 'lewd' games are too boring to play. I hope that this game can become a little gem like Bron's Quest was for me, one of the hands down funniest games I've played. I nearly cried laughing at a few points. If you haven't played it, check it out! While like this one it's also still in development, and certain parts of it also feel lacking, the humour is really something to experience.
Anyway, keep up the good work and have a good one!
