Mario did an amazing job on our Action RPG project. He worked on some of the most important gameplay systems, including boss fights, enemy AI, inventory, and player abilities…

Mario was very communicative and worked every single hour we needed him to get the job done timely.

Mario was a blast to work with and he helped the project tremendously. He was always on schedule and gave his 100% in every task that was imparted to him.
