The game will take about 15 minutes and sets the player as a German battalion CO. The decisions you make affect your subsequent options and also the ammo, morale and strength of your unit - changes to which will further affect your options.
I ran through it earlier today (it worked fine on my iPad) and achieved what I think is quite a good result, having heroically led my men in a spirited counterattack which captured the redoubt. As can be seen from the screenshot, those who survived were in very good spirits!
So why not give it a go and leave your results in a comment.
