Super Doors

Super Doors is an action game where you play as a doorman whose job is to trap all the aliens inside the doors and wait until they fall while losing oxygen, this can happen to you as well plus you have a bonus time of either 6000, 6001, 7000, or 8001 (depends on which version you're playing on) and if it goes down then the doors will generate in a different way but in the MSX version you'll be trapped in there and lose a life. You can trap the aliens in three ways like four direction door, L door, and U door but they walk around randomly throughout the maze. There's also a menu where you can turn off the sound, change the outlook of the game, or go back to the demo.
