During February 2026, SierraBay12 developed and integrated the Solar Tracker feature for the SierraBay/SierraBay12 repository, focusing on enhancing the Colony Map to help players optimize solar energy usage within the game. SierraBay12 handled the end-to-end implementation, ensuring the feature aligned with the colony’s energy system and overall gameplay loop. The work involved applying skills in game development, level design, and map design, using DMM as the primary language. SierraBay12 maintained clear commit messaging and traceability throughout the process, supporting future maintenance. The depth of the work is reflected in the seamless integration and alignment with existing gameplay systems.
