The game was published on the magazine MicroHobby as a 5 part article explaining how to develop a game. On each part a fragment of the code was published, with the idea that at the end the user could put the code together and play the game. The thing is: the code was incomplete. Not sure if that was a print error or the article was intended to be a 6 part and the last part never make it, but at the end the game was not playable. Luckily one of the authors was still in possession of a backup, that finally got recovered by RetroLEL. Go here for more information: https://www.retrolel.com/es/recuperando-ogerox/
