So I gave it a go in another browser on another monitor and it was a little more responsive.
I like the crisp shadows, as I would imagine they would be on a place with no atmosphere. Controls were still a little tough for me, but I made it much further, and most enjoyed the "race track" like portions. Oh, and the map is huge! (might affect performance?)
Congrats on another 3d browser based GWJ game! Haha..
