During my graduation, the main goal was to create a reusable puzzle system, designing puzzles and connecting them with level design principles. Afterward, I took a more professional look at the game’s core. I did this by, researching and exploring the target audience and finding references. To mix up the gameplay flow, I had to implement something else besides solving puzzles. It should be optional, entertaining for the players who enjoy this genre, and fitting with the gameplay. Adding more exploration options and different rarities of collectibles were the right choice. It works well with the game and the narrative. The protagonist is an archeologist searching for this new floating city. Once found, she started exploring it, but she was unable to find the exit.
