[9][10] The player controls OsWALD, a blue teddy bear with a bow tie who has accidentally ended up at the North Pole, and must traverse a single straight path over the sea to the finish line, jumping from one floating ice floe to another without falling into the water.

The Super OsWALD version has a multiplayer mode that allows two players to play simultaneously, while the appearance and general functions of the title screen are left unchanged.

In August 1986, Keld Jensen founded the first professional Danish game developing company, Kele Line, in Slangerup.

Most of the team left to work in the United States on Sword of Sodan at Discovery Software, leaving Sølvason in Denmark to continue the remaining projects.

[25][26][15] Starvision landed a contract with Nordisk Film to make an interactive game experience to be used in the weekly programme Eleva2ren on Denmark's newly-launched television channel TV 2, which was set to begin broadcasting on 7 October 1988.

[28] Jørgensen came up with the concept of a teddy bear jumping about on blocks of ice and collecting gift packages, as well as a couple of quotes during gameplay with the voice provided by Sølvason, including one when he loses a life, "Det var vel nok ærgerligt.

The Amiga system used in the studio was hooked to a specially-designed modem that allowed contestants to speak to the host from home, and at the same time send DTMF signals from the telephone keys to play.

[15][31] In an interview with COMputer, Sølvason stated that he founded SilverRock Productions in Copenhagen on 12 May 1989, which began operations while continuing the development of OsWALD.

[32][33][10] Despite the contract issue, the demoscene developers stuck around to work on the game, with Søren Grønbech joining in and doing additional programming.

Sølvason and Ester Grønbæch Jørgensen provided the voices of OsWALD and OsWALDLine, and Marc Friis-Møller programmed the game's intro.

According to video game preservationist Allan Christophersen, Sølvason was a narcissist and habitual liar who would take credit for his team's work while blaming them for anything that went wrong and being paranoid about people trying to pull a fast one on him.

[36] Villadsen knew a programmer named Uffe Jakobsen (who later worked on Hugo[37]), who helped him with some timing and grid routines.

In connection with an exhibition at the Post & Tele Museum, Jakobsen made a DTMF-to-joystick adapter for visitors so that they could play OsWALD via a telephone in the same manner as in Eleva2ren.
