Cubes is a modded parkour map with 25 different levels. The levels are split up in three stages which include different challenges of shifting difficulties. The stages include static blocks, mobile blocks and then lastly blocks triggered by pressure plates. As you get further into the map it gets even more enjoyable as the structure and mechanisms of the levels changes.
When you continue through the map and complete more and more levels, you will get to the next stage which include mobile blocks. As you can see in the image above some of the blocks disappear and reappear every one or two seconds.
