Abstract
The inspiration for this work comes from the belief that computers can do more than perform computational tasks, but rather tackle a concept that most people think is impossible for a computer to achieve, due to being unique to the human being: Creativity. To demonstrate this, the proposed solution consists of a level design tool with co-creativity at its core, this is achieved by presenting the user with suggestions of possible modifications to their current level. There are two types of suggestions: level layout and lighting. Level layout consists on which tiles a player can walk through or not. And the latter, lighting is how each part of the level is illuminated to provide the player with the best experience possible. These suggestions are generated by genetic algorithms with parameters that can be adjusted through an user-intuitive interface, either it being more evolved towards level layout or the lighting setup.
