"Cops and Robbers" is a fun chaotic game, which is simple to play and addictive.
It is a variation on the running platformer genre, with a twist - which is that you are always chasing a robber across the randomly generated scenery.
The robber can be caught by catching up with him, and also by reducing their health to zero. You have to arrest each robber a number of times before progressing to the next level.
All instructions are explained in the game via short cutscenes, and a simple tutorial overlay appears to describe the basics when first played.
