Difficulty done right. Very fast iteration time between death and trying again keeps you in the zone and wanting to go again. There was one spot where I really felt like we needed another checkpoint, but that might be me being a little salty about that one area. A frame or two of coyote time would help, there were definitely times where I felt like I hit my jump right at the edge of the platform, but actually ended up double jumping in the air instead.
This is so good that these complaints are REALLY nit-picky. Well done!!
