I always find it tricky to rate SpeedIF games. They were written under very tight time limits; so should we rate them for what they are, or for how impressive they are given the time limit? In the end, I lean towards the former; here at the IFDB we are no longer in the competition context, and what the review should indicate is whether the game is worth playing.
In this case... well. The Courier Who Missed Me is a very short parser puzzle game in which you need to get some secret plans. There are only three locations, and basically one puzzle to solve. This puzzle doesn't make much sense. It is of the 'use the objects and these people because they happen to be present and then something illogical but useful happens' variety. The game is bug free and competently done, but I can't say I got anything out of it. So that means a single star.
