An ice age wiped out the world. The last of humanity rides an everlasting train. There's just one problem: people won't stop reproducing. As population control officer, your job is simple — keep the population under 200, or humanity’s final chapter becomes a crowded, screaming mess.

OBJECTIVE

Survive as many years as possible aboard the last train on Earth while keeping the population under 200, or it’s game over.

CONTROLS

1, 2, 3, 4 — Switch your abilities.

Mouse Left — Use your ability.

Q — Move to the train car on your left.

R — Move to the train car on your right.

NPCS

NPCs will occasionally try to mate — you’ll know when you see hearts above their heads. If you don’t stop them in time, they’ll produce a brand new NPC.

Normal NPCs — Move slowly, reproduce occasionally.

Alphas (ones with long hair) — Move fast, reproduce often. Prioritize controlling them.

Abilities

1. Expose - Stop all mating in the target area immediately.

2. Tranquilize - Lowers mating chance in the target area. 

3. Advertise - Place a sign in a train compartment to reduce mating over time. 

4. Finger Snap - Instantly banish half the population.

Was too lazy to make a main menu and a lot more features, as well as the game not pausing on the upgrade screen lol
