The story and characters are very interesting.
The art and general aesthetic is incredibly charming.
The gameplay is good, learning to read enemy patterns is fun and all, but movement (in battle) can feel a little unresponsive, especially since you can't move for quite a bit after attacking and there's no real way to tell when pressing left/right will have any effect, so I end up mashing a button to move (though I've realized now holding it is an option as well, but still not very elegant). This is by no means professional advice, but I feel like the 3 boxes below the player could make for an easy communication shorthand. Making them a little darker when you can't move and highlighting the one you're currently bound to may make it a lot easier to read and could probably be understood with zero explanation.
Good luck going forward!
