The idea behind the Jack the Block game is simple: get higher to avoid hot lava which is getting higher with time.
Roll, jump, slide, use mini copter, elevators and other blocks to get to the white teleport block.
Before you can teleport to the next level you have to pick up ALL golden blocks floating around the map.
To score higher you will need to push on time and pick up also red blocks. Thats more difficult naturally.
You steer your character by balancing your phone left and right. You can jump or fly by touching the screen. You can use double jump which is higher and longer by touching the screen again while in the air. Your double jump will regenerate when you touch something.
You can climb walls by balancing your device to the direction of the wall and pressing jump.
