How many GB is Observo?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Observo is a short third-person survival horror game styled after early-2000s game classics, with a focus on atmosphere, puzzle-solving, and light combat.
