Fun! The player controller felt smooth, and it was very flowy to just be bouncing all over the place. I had only one issue with the control scheme, which was how unforgiving it felt to try to chain jumps. The timing window for it could be more lenient.
Level-wise, the world's design was interesting and unique enough to keep me wanting to explore. Keeping an eye out for secrets was exciting, and I enjoyed that the simplicity of the "puzzles" led to more emphasis on movement. I wish there had been a couple more checkpoints underground, specifically in the castle, because I kept falling all the way down (usually on parts that required chain jumping) and eventually got frustrated enough to stop playing.
Very solid game!
