Lock'em Up

Lock'em Up is a puzzle game where the player has to help four creatures (square, circle, triangle and cross) escape an underground labyrinth. Each creature can only leave the labyrinth through their own exits and if they run into each other they explode and the level has to be restarted. In the labyrinth there are a number of arrows and the creatures can only move over one in the direction of the arrow. It's the player's task to change the directions of the arrows so that the creatures can reach their exits without colliding with another creature. On some levels there are doors that needs to be opened with a switch and monsters that try to eat the creatures.
