On one silent night

from a gust of wind

came an earthquake

Game Concept Dynamic 2 player puzzle game. Environment – the thematic setting Solve puzzles through experience and logical thinking. Retrieve as much evidence as possible, to complete the mission.

Characters Good Profile –Scientist/Diver/Agent –Evil’s Overseer/Teacher –Mission: To retrieve as much evidence and valuables as possible and return them safely for further investigation.

Evil Profile –Scientist/Diver/Agent –Good’s Protégé –Mission: Steal as many valuables and evidence as possible for power and destruction.

Background Story: A submarine has been sunk by unknown reasons. To investigate the cause of this, Dr. Equistian has set an expedition with Dr. Horse, to find out the causes for the accident. Having found from the first dive, that it seems to be an inside job, they both set forth to explore the inside of the submarine to find clues. However, Dr. Horse is not who Equistian thinks he is … ”Once upon a time blablablablala” (maybe video clip ) There is something crazy lurking in the submarine. The submarine is in fact playing games with both players. Giving them puzzles to solve the codes to the doors is one of the ways the submarine is finding very humorous. What is this thing that is playing games with these two?

Collect as many items as possible Use the closets accordingly, to get around faster. Collect the items and get out, before the submarine falls.

Project Process Brainstorming process –Two minutes of quick thinking and random idea generation –Logging of all ideas –Comparison and combination of ideas –Taking thoughts home and repeating the process (draw diagram for this)

Initial Brainstorm Logging of ideas Comparison & Combination of ideas 2 Minute Brainstorm Session

Prototyping Pen and Paper vs. Computer –Pen and Paper Developed a board game for this, which consisted of a timer, a sheet of paper with puzzles and covers on these. –(insert picture here)

Playtesting Procedure –Computer Playtesting Gathering of random people at the beginning –This allowed analysis of random problems –Testing of user interface Targeted specific groups –General computer gamers –General puzzle lovers –General analogue gamers

Technical Design Process Translate pen and paper prototype into technical requirements. Break down core game mechanics, choose suitable implementation/design strategy, look for code reuse. Build the rooms and example puzzles. Implemented time, air supply, rewards, doors, closets, puzzles, and fog of war.

Interaction Human Computer interaction Each user input may be defined in 3 ways. For puzzle solving: –Single selection  1 solution only –Multiple selection & OK  more than 1 solution –Ordered selection & OK  order matters

Scripts Reuse of similar code shared amongst objects. Simplification of modifying the code in the future.

Coding issues Collision detection: Gamemaker makes multiple collision events between two objects. Since we require a single event to fire, we needed to find a solution to this. For this, we attach an activation button which initiates the creation of a temporary object which makes the collision with the object, which then gets deleted after use.

Coding issues 2 Fog of war feature – inspiration from a book, where there is a single circle of view. Port it to two circles of view. Had to rewrite the draw method to draw black boxes everywhere except where the players were.

Audio Intense VS humerous Environmental samples Feedback audio Dynamic music to stimulate the mood
