Technically mindblowing for what is mostly a one-person project, with arresting visuals and great music. The early levels are more effective at horror than most actual horror games and, while not fun in the slightest, the spaceship sequence may very well be the most impressive thing I've ever seen on the Source engine. There are even sections with alternate paths leading to entirely different sets of maps from each other!

G String is a clear labor of love with an unprecedented amount of effort and care put into it, but the experience ultimately feels hollow when you reach the ending in which nothing is accomplished and suddenly realize that over half the game was a sewer level. Very little of the gameplay is particularly good or memorable, even if the world design surrounding it is the polar opposite. This is an undeniably interesting piece of art from a creator with an extraordinary vision and immeasurable persistence, but not one I think many people would enjoy. Which is okay.

Remember: having one auto-turret is enough, two is a problem and three is illegal.
