The game needs flash 15.0.0 (or newer), due to the latest added support of gamepads (and some other memory related potential issues)...

We forced the update since it will also make the game run smoother, solving the 'sticky keys' issue of some players.

The game will work even on a somewhat older version (11.8.0 if I'm not mistaken); However, since the new versions deal issues that some players have experienced in-game, we prefer forcing the newer version (if players start playing on an older version, and have sticky keys issues, they will most likely not look around how to solve the issue, and just leave the game altogether).
