Writing as I play.
No controller support? (Sad emoji). Tutorial so far looks great. Good job. Fantastic art. Inside the combat, the game is black and white, so extra care needs to be taken with the UI. It looks good so far, but identifying which character had the active turn was a bit tricky at first. I think you should on top of highlighting the active character, make the other characters slightly darker, when they are not active.
AOE atacks, like rising slash, still doesn't communicate that they are AOE, except though the text. You should invest in informing it through the UI as well, like in Darkest Dungeon.
Enemies can cross gaps, they don't follow the same rules as the player? Also, I couldn't find a way to "pass turn" in the map, to let the enemy come towards me. Is this intended or was it explained somewhere and I didn't read it?
I think enemies should not be able to cross gaps, and that I should be able to skip my turn in the map, to lure enemies to my range, and be able to strike them first.
I think those are my 2 cents so far. Good job!
