Only played the test levels.
For whatever reason the logic just clicked, so I found the difficulty to be on par, maybe even a little easier than the main game. So fairly easy levels, with one or two that I got stuck on for a bit before the eureka. The harder ones this time were Bridge2, Bridge3, and the bonus stage I think. The moving planet in the BG was a nice touch, looked nice without being distracting.
Good job, hope to see more puzzles, or even an official look for the witch fairy next time.
