Cloudbuilt is a speed-run, parkour action game set in a desolate landscape. What that means is you are expected to run as fast as you can through ruins whilst blasting enemies. This is harder than it sounds. Each level plays the same with jumping between platforms, using your limited booster to wall-run, shoot the odd enemy which may-or-may-not shoot back, pass checkpoints and race to the finish. There is no clock on the HUD, but at the end you are shown your time - deaths add time - and a ranking. The levels often have two or more ways to get through them, so you can get a better time or remember them for the Fragile and Pathfinder runs.
