The ark can't carry everyone.
You are the acting commander of a crew stranded on a frozen planet. You have sixty days to build an ark and make the launch window, but there are not enough seats. Draw up the list, tear the city down for parts, or hand the hard calls to NOVA. Every choice is yours.

Gameplay
Sixty days, one ark
The camp has to outlast storm after storm. Oxygen, food, water and heat all run low, and the forecast only tells you the worst case. Rationing and sending crews out into the snow are your orders to give.
The day of the list
The day the hull, main engine and navigation are done, everyone can count the seats. Once the list is out, people beg for places, hoard food and rush the launch pad.
Everyone has a name
Crew members have names, traits, relationships and stories of their own. Who got hurt and who stayed behind is written into the ledger at the end.
Trust NOVA, or govern yourself
Hand your judgment to the camp's NOVA, or take the human path. Each path's protocols cut deeper the further you sign, and the last page of the ending asks: was it worth it?
More than one way home
Besides the launch there are two more routes: staying behind through the long night, or the ship that came before. Short runs roll different planet traits and cold-wave levels every time.

Under the hood
Rules and rendering are fully separate and the simulation is deterministic: same seed, same inputs, same result, every time.
137 3D models are built procedurally by Blender scripts. Devices without WebGL2 fall back to a 2D renderer and the game still plays.
In-game sound effects and music are synthesized live with Web Audio, and the score is generative.
An automated player runs full games on a fixed set of seeds and the endings are snapshotted, so every rule change shows up.
