Algodoo

I took me a long time to do this, and it doesn't look too well because my computer was lagging from the massive size of this thing. It has a ton of obstacles, and like 20 different rooms, including an art gallery. I'm proud of myself.

The controls:

First car- Left and right arrows
Lift key 1
Second car- J and L keys
Lift key 2
Third car- A and D keys
Lift key 3
Draw Bridge- Z and X keys
Both Elevators- Up and down keys
Lift on top castle floor- N and M keys

Please comment and tell me what you think!
