This was neat, but I think the concept could have been implemented in a much better setuip - for example, if all the blocks were smaller, you could do much more. it'll also be much more impressive if it wasn't possible to slice the screen to 'red area' and 'green area', sort of

i tried making it as 1 pair would not be able to move at all till the very end where one block would remove it but that pair did not leave so i put more pair but that pair would be removed much earlier so i ignored that idea and thought of making green blocks and bringing them to safety and i succeeded so i put that in

This is actually pretty neat. I like how everything is one big chain reaction, just I would work on it by trying to make all of the green squares be involved in it, but other than that, it's pretty neat.
