In the late 90s German developer Hidden Treasures created a well-regarded Defender game called StarRay (known as Revenge of Defender in the US) and the Amiga conversion of Prospector In The Mazes Of Xor for Logotron.

After this the team were working on an original game called Randolph the Robot, a platform shooter. Development of the ceased and the team split, leaving the game incomplete. Hidden Treasures' programmer Erik Von Hesse recalls the game and answers some questions about it.

Although the game was unfinished a demo may exist, but has yet to be found.
