The MSX version saw release in Japan by Hudson Soft and in Europe by Kuma Computers Ltd in 1984.

[1] In the Famicom version of the game, players have to unite two penguins, Gurin (male) and Malon (female), who are in love.

Je te veux by Erik Satie is the background music in the game during the levels.

[2] Cobwebs occupy some of the cells on the playing field, possibly slowing the player down long enough for a spider to kill either Gurin or Malon.

With each level arranged on a 10-by-15 grid and a vertical wall separating the two penguins from each other, only the upper central cell is free for both characters to reach.
