Bullet hell

A bullet hell Touhou inspired game that was made using a self created math library and Raylib. This included Vectors, Matrices and Scene Graphs.

This game was very hard to optimise as it was the first bullet hell I had created. The patterns the boss could fire were limited by this factor. The AI of the boss consists of selecting a random direction every few seconds and moving in that direction. The boss is able to choose the same direction it was already going and will continue in that direction. The patterns swap depending on the bosses HP.

To optimise this project, using an object pool for the bullets would help in reducing the cost of the game. This would significantly reduce the need to spawn and despawn objects and I could pull already active bullets that will miss and use them instead. The sheer amount of bullets also limited the frame rate and could not figure out how to solve this since everything was drawn every frame.
