"Frustrating" is definitely an accurate tag (I had fun though!). The ability to fall back down to the previous section gives me "Getting Over It" vibes.
I, personally, dislike the way the movement works after your angle is changed. It's highly confusing (I did get use to it though). Also, the character occasionally gets stuck in the wrong direction when coming in contact with corners.
The level design was good, especially the 4th section, up until the 8th section. Section 8 was awful. The random yet super close blocks placement made the character movement erratic and the physics break. After falling from the section, the character remained broken.
Overall, great concept but not best execution.
