Radosniak contributed to the wiktorczernik/gmtk-2025 repository by developing core kart driving systems and road asset tooling in Unity using C# and physics programming. Over two months, he established a test-road pipeline and implemented features such as acceleration, steering, drifting, and physics tuning, enabling repeatable asset validation workflows. He addressed critical gameplay issues by refining vehicle alignment and handling, and resolved a wall collision bug to improve kart stability and predictability. His work included input handling, prefab modification, and audio integration, resulting in more robust controls and a solid foundation for future features, supporting efficient iteration and enhanced player experience.

In 2025-08, delivered core kart control enhancements and a wall-collision bug fix for GMTK-2025. Key features: - Wall collision handling bug fix: velocity reset to zero on wall impact to prevent momentum transfer and improve stability (commit 7133515a0c4fbed07b54653ff9af4a3d83bd0a75). - Kart control enhancements: bumping/pushing mechanics, refined alignment, driving toggle, removal of jump mechanic, and related audio assets (commits cf62db2935653efaa2297e6691063d9c8a73e3df; 13c533c0937bcbf800d939e8947143e5cc6b15aa). Major bugs fixed: Wall collision stability issue. Overall impact: more predictable kart behavior, improved player experience, and a solid foundation for future features. Technologies/skills demonstrated: gameplay physics tuning, input/controls design, collision handling, audio integration, and incremental refactoring. Business value: enhanced player retention and quicker iteration cycles due to stable controls and ready-to-ship features.
