Jarowmr
Jaro Rutjes developed core gameplay systems and UI features for the lonkaars/crepe repository, focusing on physics, collision detection, and a configurable coin economy. Over three months, he refactored the engine architecture to support deterministic physics with fixed-timestep updates, expanded collision logic with layers, and improved scene and HUD management. Using C++, CMake, and JavaScript, Jaro enhanced code maintainability through Doxygen documentation, formatting, and modularization. He delivered gameplay improvements such as end-game flow, replay, and scoring, while stabilizing build systems and addressing critical bugs. His work resulted in a more reliable, maintainable, and feature-rich codebase supporting rapid iteration.

Jan 1, 2025January 2025 performance summary for lonkaars/crepe. Delivered a comprehensive set of gameplay, UI, and stability improvements that enhance player engagement, economy balance, and build reliability. Key features were implemented across coin economy, HUD visibility, end-game flow, and UI polish, while codebase maintenance and critical bug fixes stabilized day-to-day development and QA. Key features delivered: - Coin System Enhancements: randomized coin drops, persistence of coin amounts, and updated coin configuration to support a configurable economy. - HUD and FPS Enhancements: new HUD initialization with a dedicated FPS display and a live FPS counter for runtime performance feedback. - End-Game Flow, Replay, and Scoring: added end-of-game sequence, replay functionality, and endgame score display for improved player feedback and replay value. - UI/UX Polish: grey color theme, camera adjustments, popup windows, credits UI, and button color enhancements to improve clarity and aesthetics. - Codebase Maintenance and Features: ongoing refactor and file organization, includes cleanup, and merge hygiene to improve build reliability and future iteration. Major bugs fixed: - Audio End-of-Level Bug Fix: resolved audio stopping at the end of a level. - Includes/Code Cleanup: fixes to include directives and general cleanup to improve build reliability. - Enter Key Interaction Cleanup: removed unintended enter-key behavior to prevent accidental input. - Disable Time Change: prevented time changes during gameplay to preserve game state. - Delete Replay: cleaned up and removed obsolete replay functionality for clarity and maintainability. Overall impact and accomplishments: - Strengthened player experience with a cohesive coin economy, responsive HUD, and satisfying end-of-level feedback. - Increased engineering velocity through codebase maintenance, cleaner includes, and merge hygiene, enabling faster iteration and fewer build-time issues. - Improved QA and stability with targeted bug fixes across audio, input handling, and gameplay timing, reducing runtime edge cases. Technologies/skills demonstrated: - System integration across gameplay loops, UI, audio, and persistence. - UI/UX design and polish (visual theme, popups, credits, button styling). - Gameplay programming patterns (end-game sequencing, replay scaffolding, scoring display). - Codebase hygiene: refactoring, file reorganization, include corrections, and merge management.
