In TripTrap, you are a mouse who runs around the maze. He runs in a straight line and you can’t make him stop or turn around. If he reaches a corner he just curves around it and continues walking upside down or upright. You can make him jump from one platform to another directly above or below him and that’s the only control you have. After a few levels, you also get the option to make him run faster.

Scattered around the maze are obstacles you have to dodge to collect the three pieces of cheese in every level. The dodging becomes tricky since you can only jump from platform to platform and can’t stop or turn around.
