This game recalls the golden age of video games (1980s) when gameplay was king. Back then, graphics and sound were primitive, so authors had to focus on developing a great *game*, with responsive and intuitive gameplay rather than dazzling visuals and sounds. The amazing thing about Argonaut is that the author seems to have started out with those basic ideas in mind, but then added great graphics and sound effects as well--the sound effects in particular are excellent, with multiple randomly-selected effects even for the explosions, which in a subtle way reduces repetitiveness while playing. There are many other small touches which add up to an addictive, immersive experience. I also appreciate that the controls are simple, and that the weapon choices are few--far too many mediocre games try to improve themselves by tacking on lots of extras. Argonaut keeps it simple and finds a very effective balance between rich gameplay and simple operation.
In short, this is the best game of this genre that I have played in years.
