Oh ya, here's a suggestion:
Throwing a million push/pull blocks in room is not fun. I'd say if you ever want push/pull blocks to be challenging without putting a million in a room(and the only thing that challenges is your patience), is to adopt the push/pull blocks from Zelda, and only allow one push/pull. I know it's not exactly "Graal Classic" but I think it'd be one of those changes that are actually for the better. Zelda's block puzzles could sometimes stomp for a good few minutes, and only consisted of a few strategically placed blocks.
