What the heck happened?
After exiting the ART level with the click on the "back to Main menu" icon, I clicked to Tweet the game, and it entered into an infinite re-start loop, showing only the 1st frames of the 1st lvl alongside it's entry sound, in the immediate frames shows the share game menu, then re-loops everything over and over... Unplayable ATM even after a few CTRL-F5 and even a re-boot... -.-
