You can continue playing it using a Flash player or downloading the EXE files.
It will probably be a problem only for the online versions.
no actually if you go to the adobe website they're a FAQ... long story short after the 31 december:
1) All flash payer ( no matters the version) sil cease to work
2) due to 1, the adobe program will ask you to desinstall the program on your computer ( PC, inux and Mac +...) if you don't the program will do it after the 31
3) since flash will cease to work at the 31 , you can't (already( that way i can't play Dune on my mac ) download any version on the adobe web site
4) if you are smart you will think " mhee i don't need to download it on the source site ( adobe.com) i will download it via ixc.com" well they a smater cause no matter where , when or how the program will cease to work and thus cease to exist
that why i said
"RIP behind the Dune"
cause if Balsamique doesn't change is "program runner" Flash player in this case to another ( renie, unity...)
or WSE
the game will defacto cease to exist
by the way to wh ever have read this transmit it so it can make some Noise to alert any Dev
