No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $3.9K — a different platform, not this one.

Space Robinson: Hardcore Roguelike Action

You are an ordinary engineer sent to Colony 21 located on a distant planet to perform maintenance works. You end up surviving a spaceship crash and make it to the abandoned Colony Base. While you are trying to find the answers, you understand that this place is not as friendly as it seems. You are just like a Robinson, trying to survive on a hostile planet lost in outer space. HARDCORE This is a rogue-like game. You’ll die. You will die. YOU WILL DIE!!! A million times. Then tutorial ends and you’ll get a chance to fight real Monsters. ALWAYS NEW Every single level across 3 big locations is procedurally generated, so you will always find a new spot to die! Do you still think you will survive?! But wait! If you are tough enough to storm through a couple of levels, you might make it to an outpost where you can refuel and find hints on what has happened to the colonists. NIGHT SHIFT You have somehow managed to survive the day? Don’t worry, this planet has some nightlife to offer! Experience a completely different Night Mode that will make you… DIE, of course! BOT-ASSISTANTS If you are lucky enough, you can find artifacts and create bots to help you! Start with a cute puppy that turns into a furious beast once the monsters are in sight. CRAFT AND UPGRADE Good news: death is useful! Once you die, the Colony AI will use the DNA that you have farsightedly left on the Base to create an exact copy of yourself. You will also retain all the crystals and artifacts that you've gathered (don't ask us how it happens; colonists may know the answer - ask them, when you find them). Repair the Colony units with artifacts and upgrade the reactor with crystals to energize the base. Every reconditioned unit will improve your stats and increase your chances of surviving another minute.
