I think this is basically a platformer where the focus is on free-running to try to escape the police of an oppressive society while performing Parkour-type moves to get past obstacles. I've played it longer on mobile than Steam, but assuming it's designed the same, there are three worlds with around 12 levels each (I forget exactly). As you run through them, you'll pick up cubes for points and coins that you can use to buy more Parkour moves. To get a 3-star score on each level, you have to collect all the cubes, which isn't always easy, and perform all of the Parkour tricks, whose locations are marked for you so they're easy to spot (but you still have to time them right). Since the tricks are purchased, you may have to grind for money in order to buy them. Grinding isn't really necessary in the beginning, but as the games goes on and the cost goes up, you'll probably need to do more grinding. Each of the three worlds has specific game moves, with the second and third building up a little from the first -- IIRC, the second one introduces stopping and lets you jump back and forth between walls to reach higher areas, and the third introduces reversing direction and using elevators to go up and down. For the most part, the game is linear in that most levels seem to have only one way to clear them, and it's mainly a matter of practice and timing to learn how to do that. They're usually not too long or frustrating though, which is a good thing. I'm not sure exactly how the game ends though, because I didn't finish it on mobile (I got tired of grinding after a while). But even after finishing it, I think there will be some replay value, because you can keep trying to get that perfect 3-star score, beat your previous fastest time, and/or go for Steam achievements. Also, I see a Hunter Mode in the game's menu, which is unlocked by earning 50 stars, and that new mode should add some variety and replay value as well. While I would have preferred a bit less grinding for money to buy moves, the game is good overall and I'd recommend it.
