Algodoo

Okay, I will now tell you the themes of the
first 6 checkpoints. There will be over 10 checkpoints
when finished.

The start will be regular Algodoo,
the 1st checkpoint will be beach themed,
the 2nd checkpoint will have a Mojave Desert theme,
the 3rd checkpoint will have a futuristic theme,
the 4th checkpoint will be sea themed,
the 5th checkpoint will have a mountain theme,
and the 6th one will have a forest theme.

Also this is like PinOut (did you play it yet? It's an app),
it's really fun! This is in early alpha, expect a lot of bugs!
