6 ) Mobile/Portable version of the game
Zanzarino is, at the moment a single developer, and this game itself is still being updated and improved on a regular basis.To move a game like this to the iPad would mean double the work, and as a result is quite unlikely.
Also, to create a game for the iPad, you have to buy the software necessary, or download and use the free and limiting software, which probably would not be able to recreate a game like Elements. Either way it would require much effort, learning how to use the new software and the investment into a new and expensive Mac that can run it.
