Galaxy Gate

Galaxy Gate is a puzzle game. The player takes on the role of a customs intern at a space freight transport station whose job is to inspect containers for explosives and contraband.

The player operates scanning rays of different colors that can detect different types of illegal goods. By the end of each level, the player must mark all the containers with explosives for the bomb squad to diffuse them and confiscate all the illegal goods. Opening a container without anything illegal results in a fine for the main character. There's a time limit for each level.
