About this game

The developer's description, from the game's Steam store page.

You are a Living Spark surviving inside fragile wooden vessels that splinter, collapse, and catch fire. When your vessel breaks, the Spark escapes. Death is just a change of scenery.

Ride a cursed elevator into shifting underground ruins with your crew. Smash furniture for resources or feed them into the Grinder for gold. If everyone breaks, your loot is lost.

Trolling can become your friend’s demise. Dropkick enemies or “accidentally” launch your ally’s Spark out of their vessel. Block them in a monster-infested corridor or get stuck in the crossfire. Will your group handle the chaos you created yourselves?

The deeper you go, the worse the Rot becomes. Bodies warp. Voices distort. Emotes become…worse. Or possibly better?

The Deep Layers are filled with Corrupted vessels, reacting to sound, movement, and each other in ways that are impossible to predict. Fight. Build. Run. Panic.

When your vessel breaks, you stay in the run as a Spark. Guide your team through the dark and search for another host with a new set of abilities. Force your way back in before you fade out completely.

Everything you haul back rebuilds your Outpost. Unlock interactive furniture, stat upgrades, rescued survivors, and stranger ways to survive the next descent. The stronger the outpost becomes, the deeper you can afford to go.

Go deeper. Extract more. Leave someone behind. Make it back and build together. 

Or don’t come back at all.
