Let's go in steps here.
First of all,
you probably need a controller to enjoy this game, even the game tells you that when you're opening it without your controller plugged in. I haven't tried playing with my keyboard, but with the controller you use your analog stick to do tricks, so it involves a lot of spinning it around in multiple ways and pressing buttons along to do all the complex stunts you need without really having to think too much about it. Simple to learn, challenging (in a fun way!) to master, as it offers a fulfilling variety of stunts of different levels that you can perform.
Is this another one of those endless running / distance games?
It involves distance, but it isn't endless. The game is comprised of "stages" with a number of goals you can accomplish in each of those. Each stage has a certain distance, to go to the next one, usually all you need to do is finish the stage in one piece. However, you also have the option of completing one or more of those multiple goals that each stage offers. Completing all goals in a level unlocks a new difficulty of that level, with even more challenges. So it's a bit different of the boring endless distance games that have been crowding the game market lately.
Is there a story?
Sorry, not really, but even though I love games with stories, I didn't miss in this case because the game mechanics keep you hooked init. It's actually very easy to completely forget about your goals even, just because you got so excited that you got like 10 perfects in a row and you want to see how far you can go.
What else can you say about this game?
As you're playing, you learn with your mistakes, so even when you fail it doesn't get frustrating, because you get that feeling that in just a few more tries you'll get it right. Some times you'll have to stop doing the stunts you tend to overuse, and pull different strategies and combos to get the objects in the field that you need to collect to complete a challenge. There's also a big variety of stunts you can perform, as well as the techniques you need to develop to get perfect landings, nosegrinds, to get better speed without having to put your foot on the ground to push your skate faster, etc.
Yeah, it's a casual game, but I tell you, it's addictive. (I just spent 2 hours playing it nonstop, and had to stop myself because I had work to do, otherwise I would've kept going - even just writing this review makes me want to go back and play it a bit more!) My only sadness so far? I wish it had more steam achievs, I feel like this game has a lot of cool achievement possibilities, but sadly that wasn't well explored. At least we get cool in-game coals to achieve, though!
