Alexandre contributed to the Card-Forge/forge repository by expanding enemy variety and refining game balance within a one-month period. He introduced the Urabrask enemy, developing new sprite assets and defining attributes using Atlas and JSON, which enhanced gameplay diversity and challenge. Alexandre adjusted Urabrask’s scale parameter to 0.65, tuning the difficulty curve and improving player engagement. His work demonstrated careful asset management and disciplined version control, resulting in longer play sessions and clearer progression for users. Although no bugs were fixed during this period, Alexandre’s focus on JSON manipulation, game development, and sprite design added depth and polish to the project.
