One year for Christmas my brother bought a 50-in-1 game clone that plugs into the front of your TV called "Superjoy" that had this game on it. I played it for five minutes and got frustrated because I thought it was a game, and therefore was supposed to be fun.
If that bird had a character sheet and a way of leveling up people would still be playing it today, and in chairs with holes cut out so don't have to get up to poop.
From wikipedia: 'There is an ending to this game. However, reaching the end requires considerable patience because it only comes out at the end of level 999 (approximately 28 repetitions of the game's thirty-six levels).'
