All you need to do is tap the screen to jump, avoid obstacles, and keep moving forward. But it is much harder than it looks. As you progress, you will encounter various challenging obstacles. Also, don't forget about the side walls! They will close in on each other, meaning the longer you stay on an obstacle, the narrower the passage becomes. And if you don't get past the obstacle, you will eventually be crushed between the walls! But don't worry — every time you overcome an obstacle, the walls return to their original position (but they'll start closing in again!). So do your best and earn as many points as you can by avoiding obstacles without getting crushed!
