SkyClimber has been upgraded to version 2.0. The game play itself has not changed, but it now includes the ability to install "expansion packs". The first expansion is free for all SkyClimber owners, and is titled WorldTraveler. It is not a true expansion pack that adds features on to the original, but it is a separate game that builds on the original.
The WorldTraveler expansion pack includes the same basic gameplay as the original, except now there are enviromental effects on each of the stages/tiles. There are also four new unlockable balls as well as the original four (if you have unlocked them in the original version).
There are 100 free copies to be given away with the coupon code FREEAIR.
