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 $7.8K — a different platform, not this one.

Underland

The astronauts who set out in search of a new habitable planet have just returned from their failed mission. However, the Earth's surface is no longer habitable and they discover that the remaining population now lives underground. The supposed path there is buried and the only alternative is to dig and dig into the underground city. At each stage, the player must use the elements available in the environment, like the use excavators, pumps, pipes, cannons, drones and dynamic platforms to reach the next elevator. There are few ways to get there, so the player must combine the direction of the path with the physics of the elements to succeed. Thus, each scenario is a big puzzle that must be solved to reach the end of the journey.
