Well luckily for you I don't know what subway surfers is, so these game mechanics are completely new to me. :D
It was a bit difficult to figure out how to play the game. I'm still not sure how you're supposed to tackle the W/S obstacles. Do you need to tap the button only once, but time it exactly when the block comes at you? I kept tapping them like a maniac just to make sure. Some visual guidance would have been welcome.
