A little bit confusing initially, but ended up as a cool and challenging game. Wasn't sure how the crystals worked, or what the bird meter was all about, but eventually I realized it was about the challenges of collecting carrots and minimal jumps. A bit of a shame that the bird is a bad sign since it's such a cool and explosive ending to a level. Jumping mechanics were a bit glitchy and un-deterministic at times, but when it worked, it was a good experience.
