You know what is my problem with this game? This feels like the alpha of "Himno: The Silent Melody" and when you see it that way, a lot of things makes sense, the useless sword, the movement, the exp system, the difficulty, the procedural generated scenery, these are all elements of a rogue lite game, a genre of which "Himno: The Silent Melody" is part. I played the demo of that game just to be sure, and definitely feels that way. I don't think making use of that resources is bad, but I think it is bad to try to past this incomplete game as an independent "Relaxing game", specially when that title doesn't fit well in this experience.
A procedurally generated 2D platformer that is presented in neatly rendered pixel art and provides a soothing ambient soundtrack to relax as you run around the levels collecting experience for the achievements and wisps pleasing and modified movement. Nonetheless, there is no end goal for the game itself as the purpose is to go and play as much as one would want to. Still, the base is there and it was later used in a currently early access roguelike at the very least.
