Simple but surprisingly well conceived and told story, the twist seemed jarring on the first 6-piece run but came together quite nicely with the actual ending.
The crow enemies throughout the level were a nice bit of foreshadowing to the boss fight.
As previous mentioned, the jump height and speed did feel pretty jarring, but I'd also like to draw attention to the camera, its centred position makes it feel like you're never really able to see far ahead enough to anticipate where you're going in a given section of the map, and its perfect lock-on tracking probably exacerbated the issues felt with the jump speed.
