I don't know if I may ask the question in this section, but I am searching for a old computer game.

In the game you're supposed to collect many colour keys (green, blue, red etc) which are hidden in a kind of white room/space, it looks like a maze but it isn't. You're playing as a human dummy. You need these keys to open the colour barriers (with the green key you can open a green barrier etc).

The game is kind of 3D, but the third person camera is fixed. So if you go left you can only see its side. I've been searching this game forever, but I just can't found the game anywhere. I played this around 2000/2005 or so on a Windows computer, i must have been the Windows 2000. Don't know if this matters or not.

Any ideas?

[EDITED] Nope, I was wrong...but it's VERY generic, having keys of different colours to open doors.

No ideas about the game, but you are probably wrong about the operating system.

Windows 2000 was designed for business use, so it's unlikely that it would have been the OS running a home/gaming computer. If you played it on some company computer, it's possible then, otherwise you should look for other Windows versions.

But if you are searching some game databases and try to find Windows 2000 games, that's not going to help much, if anything at all.

Chip's Challenge was my first thought until OP said 3D and Windows 2000. I remember playing Chip Challenge (2D) on Windows 3.1 and was as 2D as it gets.
