But you can play using arrows! This possibility was listed on "controls" menu.

Oh ! I've just tried, and yes, the arrows are working. I've tried yesterday and it wasn't. Probably some "Verr Num." of my laptop (I'm not used to laptop). Sorry for the mistake. With arrows, I've played 10 seconds more (your game is too hard for me ^^" But don't worry, I never win to mine either ^^) ! Still a great game.
