In April 2025, Michael Kestelooy developed a seed-based procedural world generation system for the GDACollab/Well-Witches repository, focusing on deterministic bush placement with session variability. Using Unity and C#, he implemented seed randomization on gameplay scene load, allowing each play session to generate a unique yet reproducible world layout. This approach balanced replayability with the ability to perform deterministic testing and debugging. Michael also addressed a bug in bush generation, further improving system reliability. His work demonstrated depth in procedural generation techniques, enhancing both player experience and quality assurance workflows through controlled randomness and robust, testable world-building logic.
