Please use RPG Maker's control scheme for the keyboard controls. Placing Confirm, Cancel, and Menu so far apart is torture. An auto-run feature would also be appreciated.
I think it would be a good idea to get an English proofreader, if you don't have one already. I noticed a lot of grammar errors, some of which made the game very confusing.
As for the game itself, I like the concept of the battle system, but I felt I was thrown into it too quickly, even with the tutorial frog. You have to juggle multiple different resources all while considering how you want to approach each fight, and there's no free healing like in most RPGs, so I was really stressed out before I realized that dwarf berries respawned. Comfort being free to use but only in-battle also leads to the awkward strategy of stalling battles for as long as possible to cure everyone's mood.
I also think it'd be helpful to have a meter for HP as well as mood, as I'd often have characters get to very low health without noticing.
Overall, I like the idea of gameplay revolving around emotions and morale, as that's an interesting concept that a lot of games don't get into. In terms of the morality system, though, thus far I don't see any reason to be evil; unlike in UnderTale, you get the same rewards (if not more) from the peaceful option as from the violent one. The added option of "hurt their feelings but don't kill them" is an interesting middle ground, but again I don't see the incentive for it.
At the same time, I don't feel as intrinsically motivated to be nice as I did in UnderTale. The enemies don't have the same personality and depth of unique interaction, so I feel like I'm just going through the motions out of moral obligation than out of any true concern for them. Why exactly am I trying to comfort creatures that do nothing but attack me while I'm being nothing but nice to them? It's kind of hard to rationalize. Unless that's supposed to be the point...?
The art is excellent, though. I'm extremely impressed by the full animation on both enemies and allies, and the alternate sprites for happy and sad moods. Cynically, though, that makes me concerned that the dev time for the full game is going to take ages.
