Player 1
Use WASD. You begin as the human. Press E near a hut door to lock or unlock it, or near a tunnel mouth to slip through it. Press F beside a hut door to reinforce it (as human) or to attack (as deer).

Player 2
Use the arrow keys. You begin as the deer. Press . (full stop) near a hut door to lock or unlock it, or / to reinforce (as human) or attack (as deer). Your vision is narrow and dark at the edges.

Human objective
Survive for five minutes. Close doors with E or ., reinforce them with F or / (20 presses = +1 strength for both doors of that hut), and escape through the four glowing tunnels — each collapses after a single use.

Deer objective
Touch the human before time expires. As the deer, any action key — E, F, ., / — attacks locked doors. Better yet, sneak up on a rabbit or firefly and press an attack key to devour it for a 20-second speed boost.
