Descent
Rules of life
Descent. is based on Conway’s Game of Life.
Build a world from characters.
Instructions for this level
- Collect all the beacons.
- Avoid the wildlife.

- X / Release — catch and release specimens.
You are With.
You collect the specimens. Do it as fast as you can.
The world is full of memories of what has gone before. Memories are useful and can help you learn about where to be safe. This is the palimpsest.
Don’t touch the wild life.
Palimpsest can be turned on and off at any time.
Controls
Starts at 4× zoom and 15 gen/s. The playing area is also a trackpad: touch anywhere in the world and drag relative to where you first touched to steer With. Tap Map to inspect the intact starting world; movement is disabled while the map is open, but a running simulation and clock continue. The visible joystick mirrors your direction, including diagonals. You can still use the joystick directly. Rate and Zoom remain below the world. Use the top-right Restart button during a run. Release starts on. Each specimen collected earns one 15-glider burst; tap Release beside Zoom to fire it.
Use the arrow keys to move With; hold two directions for diagonals. Press M to inspect the intact starting world; movement is disabled while the map is open, but a running simulation and clock continue. Use 1 2 3 4 5 / Q W E R for Rate: 0, 1, 5, 10, 15 / 20, 30, 45, 60 gen/s. Use A S D F for zoom: 1×, 2×, 4×, 8×. Press Z to toggle 1× ↔ 4×, V to restart, and X to fire a 15-glider burst when a specimen has been collected. Use +/− to step through zooms.
