This is wonderfully confusing and I couldn't even find the end, but a fun game nonetheless. I think you should extend the walls at the start though, taking a glance into the endless void below isn't very nice.
Thanks for the feedback! How far did you get? I played with panoramas etc. but none of them felt right. Probably needs more ground cover. I'm hoping G4 gives us some nicer options for procedural skies.
