The game was fun for the time, but had one astounding flaw that no game developer could repeat today without risking user revolt. It allowed players to make decisions that prevented the game from being completed.
Complete dead ends with no way out. Worse, the player was given no indication they had trodden down a dead end. They could play forever without realizing they had stumbled into a locked box. The only path to freedom was a reload.
This was probably a cheap trick to make gameplay longer. Had the game killed players that took a wrong path, or just allowed them to move backwards to a previous state, the game would have been much quicker and smaller.
For anyone that plans to play this for the first time, keep a walkthru handy. The dialog is fun, the game mechanics are exasperating.
