It took me way too long and I almost quit in the middle but in the end got it done. Finally, after more then one year, the iOS version is ready and everybody is very welcome to download the game from the App Store.

I made as well small changes to the game itself, minor performance improovements and better implementation of the online maps map.
If you find a bug or anything alike, please let me know.
If you don’t want to rate the game, I can create a coupon. In this way you even dont need to pay for it 
Best,
