Good game. And Easy puzzle not confuse^^(y)

This game is broken in that it does not always capture keyboard input. Try holding down either the up or the down arrow key, the page starts to scroll.
When I click on the link on the bottom, the Flash window turns black (stays that way) and nothing else happens. The game is ok, even if some of the puzzles are unlogical. I never figured out what an "explosive line of 5" is. I really like the ability to undo moves, lets you even undo restarting the game.
