I had some ideas for blocks that could be used in various puzzles. You could make huge mazes or puzzle style games with these.
1. Push Block
This block you can push along the grid (not like a minecart or boat.)
It is crafted like:
Very simple. It could be used in a large maze. Or you could make a huge checker board.
To push it you just walk forward against it. Pistons can push it and it will slide. It had gravity and can be pushed off edges, which can also squash mobs. It can't be pushed on tall grass.
If you push it on ice it will slide.
2. Crumble Block
This block is very weak and will crumble if you step on it.
It is crafted like:
You could use it in spleef. It could be scattered around with the dirt or whatever you are using. Or you could make a long bridge over lava that you must run across. This could be used in an adventure map.
3. Weak Block
This is like the Crumble block but is made of stone, so it is less fragile.
Crafting:
If you step on it once, it will crack. And again, the cracks will spread. After five steps it will break. Mobs can also break these.
This could be used in many cool puzzle games.
So yeah. Only 3 ideas so far, but I will make more.
Good thinking, but I'd wait until 1.7 comes out to make this kind of suggestion. These are all pretty classic tropes, and there's a good chance that Notch has already thought of them in one form or another.
