I really like the foreshadowing you get from all the levels overlapping. Once I started playing with the blocks that slid into a solid platform, I realized I've never played a game that really captured the feeling of anticipation of being sucked in, when riding an escalator. One thing that stood out that I didn't like was the sound effect that played when respawning; the high-pitched squeak was abrasive. All in all, well done.
