Lethe Flow Phoenix

Baf's Guide

An introspective one, with some incongruities. Alone and moody, you find yourself snatched away by supernatural forces to a small and symbolic world of magic and hallucination, dominated by a river that flows through a desert. About halfway through the game, there's a great deal of exposition, in which you learn of your destiny to - and here's the incongruous bit - fight off an alien invasion. Well-programmed, detailed environment, a few nice puzzles, some possibility of getting locked out of victory.
