Dooors2 Level 25 Walkthrough:
1. In this level, you have to make the green ball reach the end without the red ball reaching the end.
Quickly tilt your phone/device to the right so both balls start sliding quickly to the right, then before the balls reach the first turn, immediately turn your phone/device to the left. The green ball should barely reach the turn and start heading left, while the red ball heads back to the start. Hold your phone/device upright to make the green go to the end and unlock the door.
If you mess up, get both balls to the end then press the white reset button on the ground.
Press the door to open it.
2. Proceed to the next Dooors2 Level!
