Door Door

Door Door is a platform game starring Chun, who must trap four different types of enemy aliens behind doors. As the aliens pursue him, Chun slides open a door, waits for them to enter, and then shuts it before they can escape.

Each stage is completed by trapping all of the aliens. Chun can capture as many enemies as possible behind each available door, but must act quickly because captured aliens will walk out if the door remains open too long.
