Name the video game

Answer

Is it

Anti-chamber?

For the clues:

Finding my cubes is key in this place

Progress involves finding different colored cubes that allow you further progress into the game

I could never exist in three-dimensional space

A lot of the puzzles involve impossible spaces and using perspective to shift/connect isolated blocks

Some might call me the opposite of a room

The opposite of a chamber is an anti-chamber

But my exit is right there, get to it soon!

From what I remember, you start next to the exit but have to complete everything else before you're able to leave. And going fast is always good
