No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $6.3K — a different platform, not this one.

Aery - Sky Castle

Aery - Sky Castle is a very unique flight game featuring a little bird that discovers an unknown world full of beauty and dreamy landscapes, little environmental riddles, and other surprises. It's a story-driven adventure to discover and rescue a broken world. The game has relatively slow pacing as it is meant to help people to enjoy and relax after a day full of hassle.
