Mobile App STACK4 with a D backend

[extrawurst]

Hello fellow Dlers ;)

about a week ago I released the multiplayer version of my android 
app STACK4 
(https://play.google.com/store/apps/details?id=com.Extrawurst.FIR).

The app itself is using the free unity3d engine (C#) for the 
frontend but, after quite a journey, the backend was developed 
using D and the awesome vibe.d framework.

While I am preparing a pretty detailed article about why it was a 
journey to the point of using D and how using D worked out in the 
end I would ask everyone who has access to an android device to 
test the app and give me feedback about every kind of problem you 
may encounter!
Cause apparently the ordanary android customer just downloads and 
throws a 1-star rating at you without telling you why the hell 
they are disappointed with it :(

Cheers,
Stephan
