Initially, we started with a few stories we had in mind. The main idea behind these stories were, a person is lost, looking for something/someone, explored a new place and it led back to the beginning.
Game method wise, we chose the click and point method as it is quite casual, but it could be challenging at the same time, depending on game level.
At that time, we were quite unsure of what kind of theme we want, so we played and surfed several websites, there were newgrounds.com, www.bigfishgames.com and finally, http://www.fasco-csc.com/works/white/white_e.php.
So after some discussion, we decided to come up with a Supernatural / Mystery type of game, where the user can solve puzzles and follow the storyline. Each storyline gave some clues to the game, so that was what we decided.
