How many GB is That’s Not My Mom?

2 GB

That is less than the typical Indie 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.

This is an anomaly-finding horror game where you search for unusual occurrences around the house. You play as a young elementary school boy who encounters anomalies every time he returns home from school. His mother behaves suspiciously, and strange events seem to be spreading throughout the city. Your goal is to uncover the truth behind this anomaly outbreak.
