Very large update! We'll be making more frequent smaller updates going forward.

We've added 13 new challenge levels (for a total of 50), and now split the single player challenges into separate 'solar systems'. So if you get stuck in a particularly hard one, you can go to another solar system to pass it's challenges. The challenges selection should also now be a lot easier to navigate.

Largest Sandbox change is in addition to a new level, there is now 'Avatar' third person mode. In Avatar mode you can run around the level as the spaceman character, and start creating and piloting your creation where ever you want. This is also how we see possible future multiplayer game modes working. Right now the third person Spaceman is just the regular model.

Flight physics! We now added proper aerodynamic flight physics. To use them add 'Wing' entities, then a tail to control the wings. We've uploaded a few of our own creations if you want to try them.

Better destruction physics. Parts will now break apart into pieces for crashes - and large vehicles will now break apart better in large crashes.

New parts include:
- Piston: Infinite length currently
- Ignition Rocket
- Monster Wheels
- Tank Tracks
- Remote Detonate Explosives
- Dozer Bucket
- Crane Hook
- Parachute
- Landing Gear
- Wrecking Ball
- Fork Lift

Other new additions:
- Can now rotate the creation with arrow keys in Sandbox
- Auto follow Camera system, best with flying

thanks,
