Thank you Jayisgames for this very addictive and pleasant game... and excuse me for my bad english !
I encountered two or three times the same problem like MadArgus : a flashing square, and the game was freezed.
Anything to do but to refresh. A little bit annoying when you've got a good score !
Bye
