Love the aesthetic, I live for experimental art styles, I was already interested when I saw screenshots on the thread. So far it's a very simple game, but I'm curious to see the final product.
Some stuff:
-I feel like moving outside of combat should also be controlled with the mouse, it feels odd to have to change from one input style to another.
-Add some feedback to the movement, like dust particles appearingas you move, or any effect. Movement feels bland without any motion.
-moving doesn't feel as useful, since it consumes your whole turn to do so. maybe move is always a free action, that way you can play around with positioning more often.
-out of combat gameplay is very simple, not sure what I could recommend here, but so far you are mostly just moving to get to the next encounter or cutscene.
Anyways, keep it up!
