Complete playthrough. A short and fairly simple first-person point-and-click puzzle game with a secret agent theme, Agent A generally achieves what it sets out to achieve, with logical solutions to puzzles. Difficulty comes mostly from working out (and remembering) what can be interacted with rather than the interactions themselves, as especially in the later chapters there are numerous areas throughout which the puzzles take place - which can lead to some frustration. Of course, a quick reference to a guide is an easy way to relieve that!
