This is a very quick office visualization done for a firm. It was done in about 3 days by me. The scene contains almost over 250k tris and so the viz is not really optimized. The glass and some meshes are also not so good.
Good job. I have only one comment about the operational side of the game. I played it in fullscreen mode. My instinct is always to exit from fullscreen by pressing ESC to bring the game into windowed mode, but here you have it quitting the game. Its a bit annoying because I wanted to continue walking around. Not a big deal though.
