Insane Number Run

I think I'd prefer to see this concept expanded in more interesting ways than just increasing the grid size. 4x4 is already too large. Instead, how about something like 9 polygons with increasing number of sides instead of numbers; or put these in alphabetical order; or numbers+shapes but you have to ignore the numbers; or tiles that are rotating slowly ... etc etc.

You got me to play this for about 15 minutes, so I guess it was pretty good. I usually don't enjoy memory games, but this one got me hooked a bit at least. I think the difficulty scales a bit too much though, but I suck at this kind of memory games so maybe not.

Also, it's a bit shame that you didn't implement Kongregate API. It would be interesting to sell all the results, because I have no idea how I stand compared to others. It is seriously just 3 lines to setup and then 1 line per submit.
