Here's some feedback that might seem a little rough, but as you probably know it's about refinement as one progresses in design...
a guy cheated his fiancee ; so she decided to finish her life by suicide .
The guy likes climbing , he told his friend that when he climb the mountain , he feels like a ghost/spirit following him .
Once While he was climbing the mountain he falls down and wakes up in The NO WHERE
So first the English must be perfect and inspire people to feel engaged and want to know more. I see you said this was based on a story in India, but perhaps something was lost in translation.
Try this: "There was what appeared to be a loving young couple, but the young impetuous man strayed and was discovered by his innocent girlfriend. Heart broken she ended her life. The village was shocked glaring at the young man, and he, embarrassed, heart broken and guilty wandered out of the village and up a mountain to seek solitude, so that he might find answers to his now broken life. But as he ascended and the air became thin, his overwhelmed mind began to play tricks on his reality as paranoia took over his soul, convincing him the spirit of his lost love was growing ever present and pressing down on him. This is your journey. Find your way back to sanity, or forever remain lost."
Now for the maze. It is WAY too simple. It can start out as a maze on the ground, like a traditional maze, but should really grow out of a path as one ascends into the mountains and then transform into a 3 dimensional path of different scales, death defying jumps, nail biting ledges, etc. that is as twisted and as looped as one can get as one closes in on the center of his psychological terror, adding darkness as one approaches the climax only illuminated with a torch. There also has to be a turning point, and then ultimately a place where one find solace and hence found their way back, to perhaps a spectacular sunrise shining on a new day.
The title should also change. It's about a journey, not a maze. Good luck.
