HTML table based clone of Xonix. All in a single file (with the exception of jQuery, taken via cdn).
Accept some game configuration via query params:
level: game level (higher level contains more enemies and have less time to be completed; defaults to 1);speed: movement speed in milliseconds (default is 100);objective: percentage of coverage needed to complete a level (default is 75);w: width of the board (default is 100; board doesn't scroll, so this is probably the best width you could use);h: height of the board (default is 100; board doesn't scroll, so this is probably the best height you could use).
There are also:
previous_score: last level score is passed through query param;xn: number of lives.
Those are passed via query param from level to level, so you can cheat; I don't care.
