Hi, the game is online again.
The update (version 18.104.22.168) contains the following fixes/improvements:
-Bug fix on WP8 devices when starting the first stage
-Memory footprint reduced (this was causing crashes on low memory devices not confirmed yet if the problem is solved)
-Package size reduced from 34mb to 12mb
Those who have WPhones, please download the game and play the trial. All feedback would be welcomed.
