Once you enter the simulation, you can press the icon in the bottom right corner to enter full screen. Then, you can use WASD or the arrow keys to move. Click, hold, and drag the mouse to look around. You can also drag up and down to look up and down. Once you want to exit, get out of fullscreen by pressing "esc" and select "back". You can expect more VR simulations to come! (Currently, there is only Classic Shapes.)
