A fun, simple level that’s well paced, broken into 3-4 different sections and challenges. It uses a variety of obstacles to stay interesting, and it is generous with the checkpoints. I appreciate the escalating difficulty in such a simple level.
I would consider slight more use of backdrop and terrain to tie together the floating bits a bit more. Also, if this were a much longer level, I’d suggest having separate paths for speedrunners versus jem seekers. Given it’s simplicity, however, that would be overkill here.
