Well damn! As usual, your pixel art is super well done and refined, and all the animations feel crisp. You've got the platforming mechanics and rhythm down perfect. The mechanics/physics felt just right - clearly carefully calculated in terms of spacing of platforms so as not to make it too easy or hard. I was using a keyboard to play - was a little awkward at first but after a few minutes felt totally natural. The wall hug/drag feature was nicely done, and i totally see how it enables smoother backtracking through levels, although the most absolutely fun thing for me was chaining together several enemy kills with the slow-motion attack to achieve some big jump that i couldn't get to otherwise. That feature felt super smooth and satisfying. Minor criticism: the "continue" feature doesn't seem to be working on the macosx build - if i close the application, it only allows me to start over. haven't gotten through to the 3rd crystal yet, but i'll send more notes then! amazing job!
