Robo Miner for PC features a true Fullscreen Mode.

To toggle between Fullscreen and Windows Mode just press F11 during playing.

This was added to the Steam Version of Robo Miner during it's first release week, where players said, they would like to have true Fullscreen Mode in Robo Miner.

That feature was then added to the game and now you can enjoy Robo Miner in Fullscreen Mode on your Windows Workstation! How cool's that?!
