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 $971K — a different platform, not this one.

After a century in stasis the girl En arrives at her destination: A Palace out of legend, a marvel of the old civilization eons gone, still awaiting its first human occupants. Out here, using forgotten technologies, she hopes to bring back a life that shouldn’t have been lost. But nothing could prepare her for what she’ll face in the ancient halls below. The experience starts as a character driven journey of discovery, but as it unfolds it evolves into something altogether more punishing. The Palace studies everything you do, everything you are, to use it against you. Gameplay revolves around stealth, action and manipulation, as you face off against the ultimate enemy: Yourself. 1 player Software subject to license (us.playstation.com/softwarelicense).
