The red square block is ready to be tested in Undig. You also need to choose a difficulty level from the three presented and go to the location. It is a platform built in a vertical plane. The task of the block is to jump onto the upper platform and move higher and higher. You can't miss, if the block falls, it will end up on the lower jagged platform and shatter into fragments. On more complex modes, the platforms will move in a horizontal plane. Get as far up as you can while nimbly jumping across the platforms in Undig. It is important to choose the right platform for jumping in so that it is not awkward.
