I choose the word 'soulmate' as the theme of my game. As the player solves riddles, he will meet someone who will be his soulmate. I wanted the player to concentrate on my game, so I use the way that answers with the question using prompt function. Also I recommended them to use google, so I hoped that they are interested in the way that game goes. I take a house structure that game map is composed of several rooms. There are traps that they will be moved into the first part of my game or normal rooms that can solve problems. I wanted to player to think about what love is, so I made a simple lesson in the last part of the game. I wanted to player to feel happiness and achievement as he is trying to solve the questions and getting closer to her.
