Crazy Gravity Play Online
Avoid using the Up and Down Arrow when playing without Full Screen, Instead, use W and S keys.
The game will always start with Level 1. If you have played earlier and want to change the level, click on the 6 dots icon in the top right corner.
Never click on Back Menu on the level screen. If you do so, you will see a blank screen without options. You should also try Fireboy and Watergirl.
