Blocks are very versatile objects and I find myself wanting them to be able to appear, once a switch it activated. That would open up a bunch of new options:
- It could block off a path previously avaiable to the player
- It could open up a path that was previously unpassable (by putting them into liquid tiles like water)
- It could add an element to puzzle that couldn't be be solved previously.
I don't know if this is TOO versatile to appear if a condition is met, but it seems to have a lot of potential 😄
