I only discovered developer Wadjet Eye Games last year, and through 2012, i played through Gemini Rue and their Blackwell series (and I have plans to play Resonance soon). They make fantastic adventure games, and now Gemini Rue is being ported to iOS. Here's the original trailer of the game.
Gemini Rue is a fantastic sci-fi tale set in a hostile and corrupt galaxy. Adventure game fans should really enjoy this one, and we'll let you know when it's released.
