This bachelor's thesis revolves around exploring the development of a game in the shoot 'em up (SHMUP) genre by using C# scripting in Unity. The project's aim is to understand the challenges faced by indie developers and the game creation process itself. This is achieved through implementing core mechanics, designing user-friendly interfaces, creating diverse levels, optimizing performance, and conducting playtesting. The resulting product serves as a practical example of applying fundamental gaming algorithms while providing insights into indie game development.
