That’s according to data from Sensor Tower, which estimates the free-to-play game has generated approximately $175,000 from in-app purchases on the likes of customisation items.
In comparison, the studio’s first mobile game Flower, a $5 iOS release in September 2017, has been installed approximately 80,000 times and grossed almost $400,000 to date.
Sky: Children of the Light is reportedly No.28 on the iOS games download chart in the US, No.4 in Japan and No.6 in South Korea.
Thatgamecompany bills Sky as a “social adventure in an ever-changing kingdom of compassion, community, and wonder”.
In the introductory video above, studio co-founder and creative director Jenova Chen says: “Sky is a game where we’re inspired to create these heartfelt emotional experiences shared between you and your friends.
“It is made for gamers, but it should also be playable for people who never play games.”
Sky is also due for release on Android, Apple TV, Mac, PC and consoles, with more news on launch plans expected “soon”.
Thatgamecompany‘s celebrated adventure game Journey launched on PC in June through the Epic Games store.
