Good level design. I enjoyed the variety of challenges they had like needing to wall jump but not too much or trying to jump but you got no head height and need to horizontally travel.
The art and story of cecil is top notch. Would be horse again.
Controls are interesting but usable.
For example wall jump has no indicator but you do have to move into a wall in order to jump off except when you're jumping off another wall? You can't go up angles and need to jump.
But you don't need these things to progress.
