We are happy to inform that Math Clasroom Challenge is online now on Steam, in standard and Oculus Version. But be aware that both versions are the same, so you only need to activate or deactivate your Oculus Rift device to play with VR. If not active, the game will run as usual in a standard monitor.
You can read the manual and features here.
Math Classroom Challenge will be available in two weeks. Thank you for your interest.
