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.
This is what the beginning of the first couple of levels will look like. They are very basic and include no special blocks.
As you continue through the map and completes more levels you will get to the next stage which include mobile blocks. As you can see in the image down below some of the blocks disappear and reappear every one or two second.
There are of course more existing parts of the map than this but it should give you an idea what this map is all about. If you complete the map then you can enjoy some nice fireworks!
