That was fun! It was very well polished, and it looked and felt great.
However, I felt that the nature of the game is more about experimenting to see which angles and timings work, and that the level design didn't really fit. Often times, i would get past a section only to die and have to replay the previous section, often times dying a couple more time until I could get back to the new section. Since I view this game as about experimenting, it can feel frustrating having to replay things that you know how to do, but maybe just aren't super consistent at executing. Maybe more generous checkpoints?
Either way, I found this game quite enjoyable!
