Ganymede

Ganymede is a game of logistics and real-time strategy, set on the four major moons of Jupiter.
Mine the moon surface to extract raw materials, build conveyor belts to bring the materials to processing plants to produce advanced goods, defence towers and more. Make money to improve your base by launching goods to orbit.
Each of the moons has a slightly different gameplay, at times more focused on logistics, other times on survival. The most advanced levels of this (full) version require a base that is well defended and capable of destroying the enemy's bases while at the same time generating a profit.
Even experts will need several hours to complete all the twenty levels.

We tested it on fourth generation retina ipad, ipad mini and iphone 4 & 5.

Since it's a multi-level 3d strategy game, the user experience is best on large phone screens (4 inches and more) and tablets.

Just added a little user guide, see the support url.
