Cool idea and simple visual with nice color palette :) I definitely did not expect the cool transition with the cutscene and 3d turn-based strategy! It looks really epic with the lights and effects.
However the UI/UX can be definitely improved significantly by just adding sounds to every interaction that is possible. The settings could be in a separate panel that could be accessed with esc maybe? I do not think it is necessary to see the sfx/music and controls all the time on the screen. Even some toggle off/on would help.
The animations and sprites are really good though like how they move even slightly while fighting makes it much more immersive and feels much more polished overall.
I think it is amazing what you achieved in 1 week :)
