I really dig the artstyle, I think you're really cooking with the black-and-white aesthetic.
I don't have that many complaints about the UI aside from what has already been said, but what I noticed after rewatching the VOD that the combat sequence is extremely disorienting. I don't think you have any movement frames (or they are barely noticeable) - so during combat it feels like the attacking character just spawns somewhere in the middle of the opposing party with the attack frame. I think maybe at least half a second of animating the movement (even if it's just a static sprite moving in position) would do wonders.
I'm very much looking forward to what you're gonna do with this, I feel like with the right SFX and VFX this would be a fantastic game.
