Pilot a submarine is in testing phase

[rudra]

Hi,

One of my tasks for Google Summer of Code 2017 was to port the "Pilot a
Submarine" activity from the GTK+ version of GCompris to the Qt version.
The port is complete, and the source code is available in the
gsoc_rudra_submarine branch. Link: 
https://cgit.kde.org/gcompris.git/log/?h=gsoc_rudra_submarine

The activity is currently in it's testing phase, so any form of review in
the form of bugs, feature requests or just thoughts on the implementation
of the activity will be very helpful

Few links related to the activity are provided as folows:
