Something of hidden gem in the Game Boy catalogue, Catrap is a platform puzzler credited with being the first game to have a ‘rewind’ feature. You’re tasked with defeating monsters in order to escape 100 levels of ladders, blocks and other objects. Stages get more and more devious, of course, and a level editor enables you to create your own. If it looks a little basic from the outside, the game has a giant amount of content and could keep you busy for weeks. It was arguably overlooked back in the day, but it’s an innovative puzzler that deserves a bit of attention.
