Door Door mkII

Door Door mkII is an expanded version of Door Door with an extra 50 levels (levels 51 to 100).

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

Door Door 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.
