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 $610.4K — a different platform, not this one.

Iris.Fall

Iris Fall fuses gameplay with light & shadow. The concept of light and shadow runs throughout the design of the game’s story, art and puzzles. Switch between light and shadow and pass through the two realities as you experience unique interlacing of black and white, as well as both 2D and 3D.
