How many GB is I'm on Observation Duty?

2 GB

That makes it bigger than 52% of Puzzle games we have measured.

The median Puzzle game needs 1 GB; the largest tenth start at 10 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.

Your job is to monitor live surveillance camera footage and spot anomalies in the monitored rooms. Anomalies range from furniture movement to otherworldly intruders. When you spot an anomaly you have to file a report to fix it. You will need sharp eyes and good memory to survive the entire night.
