We got our first look at gorgeous indie...racer (?) Proun last year, but the game's developer, Joost van Dongen (one of the devs behind De Blob and Swords & Soldiers), has just released a second trailer. And it's even better.
The game's currently shaping up for a Spring release on the PC. If you want, you can play a rough beta version of the game from 2009 here.
