Excellent noir atmosphere, it's full of Blade Runner references, including some Cowboy Bebop aswell. The story catch you in a way that you won't sleep before unravel it all. The scenarios are dark, perfectly made, voiceovers are perfect and the rain... Man, the rain. A bunch of pixel particles falling over my screen never meant so much.
This game could be easily compared to a perfect snowflake. It surrounded by similar ones by each side, appearing to be "one more of the same", it's small, it's fragile, but a careful look will reveal its perfection and uniqueness.
Gemini Rue is a result of only one guy's work and worth every dollar/real/pound/dinar you put in it. Buying it on a sale is a no-brainer. I really mean it.
A masterpiece of its own kind, this point and click adventure has only one flaw, its length. The game is short, very short, like the very nature of the snowflakes from my example, melting into nothing (water, actually :D). So short that makes you beg for more like a guy smashing a door of a Krispy Kreme at 2 AM for one more sugar shot before bed.
I really hope that this great game comes into your library someday.
