As requested by many users, i started adding Keyboard inputs to all controls.
In this update the Laser sailboat can be controlled with "A" and "D" for the Rudder. "Left" and "Right" for the boom and "K" for the Keel.
I know it isn't much but i have began to work intensively on the Windows version now and more will follow soon.
Once again, thank you all for the support.
