Very cool. I enjoyed the puzzles and thought the bird animations and overall aesthetics were excellent. I only really found the loop resetting a little bit frustrating in one level, where it felt like I had to use a lot of trail and error to spit the cog out at the right spot (I also didn't realise some of the platforms toggled on/off, which led to a few surprise falls/resets). But that really didn't detract too much for me - a really enjoyable and satisfying experience.
