Colin the Cleaner

In this game you play the role of a cleaner who works at a museum. The gameplay involves you collecting all the litter that has been left by school children on a school outing within a certain time limit. To hinder your task further you cannot fall of a ledge or walk down steps as this involves you losing a life. All you have to aid you are teleporters and ladders so a tactical thinking is in order to make sure you don't get trapped on top of some stairs. When you have collected all the litter an exit sign appears and you collect it to go to the next level. There are over 10 different levels in all.
