How many GB is Project: Null Hypothesis?

7 GB

That is more than the typical Puzzle game, which needs about 3 GB.

Leave at least 14 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

You will play as Elias found recordings, exploring the anomalous space with him. Uncover the sinister secrets of the Backrooms as you wander through endless corridors and frighteningly familiar rooms.
