DoorDoor

In DoorDoor , players take on the role of Chun. Chun’s goal is to trap four
different enemy alien types behind doors.

DoorDoor is a platform game in which Chun has to lock up the alien
creatures that pursue him. Chun can attempt to lock as many aliens as he can
behind each door that is available on a particular stage. Chun can slide open
a door, wait for the alien(s) to enter and then he has to quickly shut the
door, because if he waits to long the captured aliens will walk out and pursue
him again. Each stage is completed when all the enemy aliens are trapped
behind doors.
