Fours

Lame. Played this game for several hours and then had to get some sleep. I came back the next day and it started me from the beginning. Really sucks to have to start over.

I rated it 4

it doesnt know what 4!^4!^4!^4! os =(

Interesting idea but not presented in the best way as a game.

There doesn't seem to be a way to enter a ^ symbol using a Spanish keyboard (where it requires two keypresses - combining accent followed by space). Could you create an alias key for that as you have done for sqrt?
