So you are a rock going down the mountain.

A and D to move left and right respectively

One problem : the faster you go, the more pieces start falling off you, so you got to balance your speed to make it far.

There are 4 types of things that you will find down the mountain : 

1. A bush, ( the black rhombus ), which will make you slow down

2. A ramp ( the black triangle ), which will throw you in the air at a cost of a bit of your speed.

3. A bunch of speed lines ( use your imagination ), which speeds you up ( duh ).

4. Another rock with glue on it ( the cross sign ), which gives you a bit more size.

It's not balanced at all, so good luck making it past 300 m, but hey it's a *thing*
