Thanks for pointing this out. 'Twas a fun thing.
Essentially you're leaping and slingshotting yourself between floating bubbles to reach objectives. The game looks like it will be quite open and evolving with its mechanics; the first of the two levels in the demo has you following another creature to find the right route through some traps, and the second has you pinging off sonar signals to be guided to the objectives. It's a simple concept that looks like it will be developed and explored from level to level, similar to NightSky.
