Drop my box

Game drop the box!
The rules are simple:
- Drop the boxes onto the lower platform;
- Drag your finger across the screen to move the cube;
- Tear your finger off the screen to reset the cube;
- Do not let the cubes hook on moving platforms, otherwise you will lose;

It's simple, is not it?
But the game will just drive you crazy with every new level. Try not to break the phone, in an attempt to pass all 600 levels.
Have a good game!
