Running the game on Linux after Flash dies
I finally got two Chromes running on my Linux, with one being local (and it'll never be upgraded) and the other being a normal, packaged, system-wide one, that is to be updated as new versions are released.
For those interested in how to do it, I've put it here (be cause this new forum's formatting is quite lousy, and also because this link can be distributed for other Flash games to use).
The document is set to never expire and it is owned by my Pastebin account, which means that I can update it as needed.
