very nice, but i found a glitch...
if you click on one block, and then quickly click the one above it, you can clear blocks from 2 rows... heh
if that makes any sense...
im not sure if thats on purpose...
also it would be harder if you couldnt clear out a block if there is only one...
then you would have to be carful what order you destroy them
Verrry nice tho, much better than i could do
