The general idea of the game is to escape the scientists who captured you. First you proceed through the test chambers, before breaking out and going through the city/suburbs to escape to freedom.
The basic enemy types are the Grunts who are armed with an SMG (I'm thinking P90 in style) and the Pursuers who are the final product of their research into the agility tested on you, they are armed with just a stun baton to keep weight down and agility up. There is also a boss at the end of each level but they aren't classed as "basic" enemy types.
The game-play is more Parkour based than standard platformers (this includes vaulting, wall jumping and ledge grabs) with large levels to accommodate this.
You can deal with most enemies in two ways, avoidance (you pass the enemy stunning them without losing momentum) or take-downs (KOs the enemy, making them stay down but you have to stop to do so.). These will both have a QTE (quick time event) in which you hit a button in time, the avoidance QTE time is much shorter on the Pursuers (they are very agile) and the time for Take-downs is much shorter for the grunts (they have military training).
You may be agile, but you're not too tough, one hit and you go down, making the Avoidance and Take-downs more risky to pull off as if you mess up, you get hit.
Also yes, the name translates into Cat Parkour...But shush, its a secret.
