GhostSoko

The player controls a pink ghost inside an enclosed maze. The maze is filled with four types of crystals, a portal, plus four roving multi-coloured ghosts: Beige, Blue, Green, and Yellow.
The goal of the game is to collect all crystals and unlock the portal. Each assembled set of crystals receives a key of the corresponding colour.
When all of the crystals in a stage are collected, all the keys are received, and the portal is unlocked that stage is completed, and the player will advance to the next.
The pink ghost is being chased by four ghosts whose main objective is to catch him. Each of the four ghosts has unique behaviour. Beige knows the exact location of Pink, that's why he aggressively follows him. Blue is trying to predict a future location of Pink to get in front of him and cut him off. Green is the fastest of all hunting ghost. With the increasing difficulty of the game, he is even faster then Pink. With a given gift Green doesn't "think" much so he moves randomly. Yellow is a lazy ghost by nature. He doesn't care much about his duties which probably can be turned into an advantage if the player loses a focus on him.
The game is made to be cute and attractive to all players, that's why everyone can set an appropriate difficulty mode. A special Relax mode moves a blue ghost away from the maze.
With the best intentions in mind, the game is developed to bring the user a pleasant time.
