The third paraagraph should have read:

"The idea of the time release is an excellent one, but I would like to suggest a 2 square maximum, with the time release of the third, fourth, etc. I think the 2 square max. is necessary to facilitate the blendiness of the grid. There is a tendency for levels that contain 8 unique articipant contributions to feel unblendy (almost like visual tic tac toe) The ability to do two adjacent squares helps to break up the grid in a more organic way."
