Very charming style, I adore the music, and the platforming starts off simple and easy to understand. My problem is that the difficulty has a massive spike once the buzz saws are introduced. Thankfully the checkpoints, 3 hearts, and infinite lives mean this isn't too much of a problem, but it's clearly designed for you to go for that one perfect run with you losing all your gems if you die. There were a few points where it felt like I had little control all of a sudden, and a couple of the gems seem almost impossible to grab without taking damage at least.
