Unfortunately, none of that makes the game worth more than 30 minutes of your time. Its dated graphics and lack of extras (no online leaderboard to post your best times) make it more of a curiosity, the type of game that you'll play for a few minutes and never touch again. Sure, it's free, but Adventure cannot compete with the rest of the iPhone's library. That said, you should respect your elders and download it onto your phone. Just don't expect to play it for more than ten minutes.
