So, that is all about? Basically its game where you play as spirit ordered to make some shady work by sorcerer in ancient Arabic palace.
Unlike many games your character is pretty weak and petite, but invisible, so you need to play stealth, fast and try to not attract any attention. This game is unforgiving to undigested actions, you will need to be careful and smart. As you progress you gradually understand, that this palace is not that it looks and things getting much more complex...
Game features - fresh and unique style, unusual graphics, stealth gameplay, rich plot, traps, puzzles to solve and mysteries.
This game was once sold on Groupees and had very warm reaction from players. Highly recommend.
