I have trying to build a simple parkour challenge thing on blockland have done to "challenges" but it is more like mirrors edge... but hopefully the closed beta is going to come soon, and then the open beta later. (I am not really working on the buildings and details itself but the events and how it would work) Hopefully once I am done some people will beta test it and see how they like it, if they do I am going to make the buildings better and put on details so it can be ready for the open beta/release. Currently in its closed beta state there are no details and it doesn't look to good but during the open beta/release the will be details and background builds.
