I'm glad you think so!
Definitely going to have a bit of a tutorial introducing mechanics more slowly with fewer characters. The plan is 5 bosses, so there's time for that.
Not gonna change commit button to instant. It's the one thing you can do that can't be rewinded, so it should be hard to press by accident.
I can probably make it clearer though, circular bar that fills up or something. Maybe it starts partly filled and filling quickly. Not sure about End turn. Commit feels more right for the themes of the game. If there's a tutorial section where it tells the player what to do for like a turn, it'll tell them to press and hold it, and then they'll know.
Do you have any concrete thoughts of how to simplify the UI? Other than like. Making the cards smaller, and probably reducing the number of colors used to show the ranges of different abilities.
