About Stack Chaos: Alien Express
Welcome to Alien Express™ — the galaxy's worst delivery company.
You're an alien delivery driver with a tractor beam, a swinging pendulum, and exactly 5 seconds per package. Where it lands, it stays. Build the tallest tower of possessed cartoon horror objects... or watch it all come crashing down.
We drop, you pray.
The Game
Your UFO swings cargo like a pendulum. Move left, move right — the package follows with momentum and inertia. Cut the beam at the perfect moment, or the auto-drop kicks in after 5 seconds.Drop fast = more points. Drop risky = even more points. Drop wrong = total chaos.
