I liked the demo a lot and its aesthetics are very pretty. But I've also found the combat a bit rough around the edges. I have also felt that many times I did not receive feedback for some action, such as hitting a box that disappears instantly. Another thing, perhaps something that is more personal, is the glide key that I see as more intuitive to put in the same key as the jump key. I hope you are doing well and that the feedback I am giving you is useful.
