I remember buying the book "Games for Your Atari," which this game comes from. The author said he was a professional programmer, so I was expecting high quality programs to type in. Suffice to say, that was never really the case. The printouts were very hard-to-read dot matrix quality, making it difficult to type in and proofread. There was also illegible areas, making it guesswork the rest of the time.
I must have spent hours/days typing this program in to no avail. It would never run! It was one of those programs where you had to enter a ton of numbers via DATA statements to create an executable. If I recall correctly, the author promised you would get a commercial quality game or something you'd find in the arcades. That's a bit of an overstatement! When I finally a got a working copy of the game, it was fairly simplistic, not unlike a half decent 2600 game. The game itself is you controlling a little skier and touching flags for points. It's also unforgiving. If you hit ONE tree, the game ends.
