In the Fullversion you get 5 instead of 3 lives, 1 red bomb to skip a difficult level and free color selection of Simio-Spaceships.
As a programmer, I would be very pleased to get supported by you, by buying the Fullversion. With this purchase, you can contribute in this game. Requests for new level can be sent to us via e-mail. These requests are published on Twitter, so that all interested people can vote for it. The best ideas will be implemented by me.
Now have fun with Simio-Invaders!
