Note from the author when the game was released to the public in 2016:

This game was originally created for a contest I organized in 2012. The big prize was a Falcon 030. All the people buying the game automatically entered the contest, and the winner was randomly chosen between all the buyers (the final drawing was filmed and put on youtube). The winner at that time was a french guy called 'ManuM'. This game is now released for free to let everybody enjoy it !
