Algodoo

O quest is traditionally played on a single gravitational axis, but this World will be played without gravity on, but rather on a series of small "planets" With their own gravitational pull. Using arrow keys, navigate the system. At each planet's core, there will be a cannon to shoot out of. Wait until the cannon and exit are aligned along the director, then fire to the next planet. Each planet has a symbol that tells the key you need to press to fire the cannon (credit to Rusinventor for the code)
Enjoy!
