This is a port of Einstein's puzzle (see http://games.flowix.com/en/index.html ).

The mouse buttons are emulated by the A (left click) and B (right click) buttons.
The right click can also be emulated by holding one of the shoulder buttons and tapping on the screen.
This behaviour can be inversed in the options.

The mouse cursor can be hidden in the options.
