> Controls
The main controls are meant to be either played with one hand, or the RPGMaker controls. But I'll add Enter and Space to always be select as well.
> Select to advance text
Good idea, I'll add that as an alternative (select goes down, cancel goes up).
> Art for the enemies
No, enemy art is final. Primarily due to laziness, but the sketchy style also fits the Madoka labyrinths.
