Is there a way to just watch it like a movie instead of playing?
There's one on youtube, but part 2 has been taken down because of nudity...

I haven't played the game but I love Spoony's legendary riff on it to pieces. Last I checked, most or all if it was on YT, and if not then check Spoony's own site.

I would imagine there are playthroughs of the game online, so if you just watch someone playing it that's like watching it like a movie.

Edit: Now I know there are playthroughs of the game, but unlike TentacleMayor, I would NOT recommend watching Spoony's. Saxcat20 does a pretty good LP of this game; that's the LP that I'd recommend watching. I don't know if it's the best since I haven't wtached every LP of the game, but Saxcat20's LP is MUCH better than Spoony's IMO.
