First off, this is NOT the infocom version. This is a version for the C64 with a two-word parser. It's tough to play a game with an old parser. Words such as "give" and "eat" are removed and a big part of the game becomes figuring out how to accomplish tasks using commands the parser will understand. (Spoiler - click to show)I struggled to figure out how to turn the gun on. It turns out that the command "on gun" does the trick. The game also suffers from a general lack of direction; it's tough to figure out exactly what the goal of the game is.
The game does know the word "help" and generally responds with unhelpful quips like "This is no time to be quoting Beatles tunes." There is also a basic maze in the game. Also, a note to anyone who might play this game in the future: the phrase "We're not Arcturian Megadonkeys, fellas" means that your inventory is full. Since that response first occurred when I attempted to pick up an Arcturian Megadonkey steak, I was convinced that the game was bugged until I happened to drop another item.
I'm left with the nagging feeling that I might have missed something in this game. I wish I could have gotten farther.
