Technically this is also to prove to myself that canvas performs very well in all newish browsers, even some mobile. So far this is actually "playable" on the ipad1, might change when more logic and "action" is incorporated.
Also I started doing a multiplayer version (node.js / sockets.io) since this should be an ideal candidate for doing something that actually works, since predictability should be very high. I'll update if it ever works, especially interested in something that works on a 3g connection.
Here it is. Sometimes you get stuck in the beginning, just reload. And no, you can do nothing but jump around. Should work on touch devices as well:
