This thesis presents the design and development of Formidable Fortress, an artillery game featuring a rule-based Dynamic Difficulty Adjustment (DDA) system. Traditionally, games offer static difficulty settings at the beginning of the game. This method does not consider that the player’s skill may improve during the game. DDA dynamically adjusts the game's difficulty to match the player’s skill level and performance. This study explores a rule-based approach to DDA. The system has an initial evaluation phase where players from all experience ranges face the same level. After this evaluation, the game identifies the player’s level and starts acting accordingly. The game was developed using the Unity game engine, and art assets were created in Aseprite. Playtesting sessions were conducted with interviews to evaluate the effectiveness of the rule-based DDA system. Qualitative feedback and observational data were collected to check player performance and engagement and identify design issues. The results demonstrate that the system mostly successfully adjusts difficulty to individual player skills after the initial evaluation phase. Limitations were identified from the player feedback, where experienced players found the initial skill evaluation phase overly simple. The study concludes that a rule-based DDA approach provides a practical solution for adaptive gameplay. This system may work in small-scale projects or games with limited computational resources. Future research should explore how to determine players' skill levels more efficiently and how to reduce the designer’s workload.
