on the left hand side, you can see the viruses (green), and the power ups (pink). on the right side, you can see part of the tree of life and where you would be placed as a player. in the background there is an ambient planet to provide the feeling of moving within the scene.
even with a (pretty good) computer setup (i7, nvidia geforce 9700, 32 gb ram), at the beginning we had a hard time getting enough frames in vr to make it feel smooth so that you can prevent the motion sickness people often tend to get within a vr environment. to overcome this problem we used the valve shader plugin for unity which - out of the box - increased our frame rate for about 100%. also we found out about unity vr tool kit, which is a (really great) open source tool to help your interaction with objects in vr, receiving button event from the vive controller and much more. so if you are new to vr game development, i would really recommend you try these plugins.
