How many GB is Thekku Island?

8 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 15 GB free: games need headroom to unpack updates.

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

A chilling psychological horror set in 1980s Kerala. After weeks of silence, you arrive on a remote island to search for your missing wife. Explore an abandoned house, uncover local folklore, survive haunting encounters, and unravel the island’s buried secrets.
