What does it mean to "slide down 50 blocks of sandstone in a dingle game"? I see that sometimes I'm making progress with it but I cannot for the life of me figure out what I'm supposed to be doing.
The sandstone is the block that disappears after you walk over it so you have to do that 50 times in a single game. If you pause the game you see how the progress over the mission bar is increasing as long as you achieve it. Thanks for playing it!
