I made this game in Unity for the Oculus Rift headset. Stack the blocks as high as you can without it falling down. The record is about 8 meters, marked by a red halo high above. The higher you go, the more the tower waves around, like a skyscraper. I made the models in blender, coded it in C#, interfacing directly with the OpenVR API for controller input, and assembled it all together.
