Okay first the good:
The art is amazing. It is very thematically consistent and feels super professional. The animation is nice to look at.
The sound design is also pretty good. Gives the game life.
Now the not so good:
The difficulty is too hard from a frustration/direction/controls standpoint. I mean that the direction you are meant to go in is not usually made clear. Eventually you figure it out through trial and error. The controls are confusing at first. I would have appreciated the ability to edit your control scheme.
I got stuck on a portion of the game for a long time and couldn't figure out how to use the ability.
