Play Door Door Online
Trap aliens behind doors in this quirky NES platformer. Time it wrong and they'll come right back out chasing you.

Game Overview
So Door Door is this weird little NES game where you play as Chun, a guy whose entire job is trapping aliens behind doors. Sounds simple, right? But those little space jerks are quick—you've gotta time it just right. Slide a door open, lure them in, then slam it shut before they escape. Mess up and suddenly you've got four angry aliens chasing you again.
The stages get trickier as you go, with doors placed in awkward spots and aliens that move faster. I kept getting caught at first because I'd panic and close the door too early. Pro tip: watch their movement patterns—some aliens hesitate before entering, so you've got to be patient.
