Exactly 7

I think it would be nice if I could drag the mouse to toggle several squares in a line.


my finger hurts and im only on level 7 nooooo

简单的关卡不知道规则就过了，复杂的关卡过了都不知道规则

Very nice game. That last level took me more than an hour, I think.

omg that was insane.  But a whole lot of fun!  (I did find a few of the levels, 6-6 in particular, 7-7 to some extent, I think maybe another one in the sixes, to be incredibly hard simply because it took a lot of experimentation to even score a single point.  I can imagine putting in a "hint" button that would generate a random one-point-scoring configuration, just to have a starting point.  Then again, I got through it without, so, you know, maybe not! :-) )

Is it possible to add a save feature using localStorage, and maybe a level select screen? If I quit or even accidentally refresh the page, all progress is lost.

fun! clever ideas that were fun to discover in all the levels.

I enjoyed! good game.

Cool game concept!
