I've been working very hard on this advergame for 1D4 website. It's a realtime 3D game running on all the browsers thanks to webgl and it could be use with VR visors too. From Game Design to 3D modeling, texturing, lights and some in-game mechanisms. It's still a demo version at moment but I am really proud of the result.
In the next update there will be all the characters, music and interactive objects but you can already have a walk inside.
