Léo Nantermoz

Master's degree student
in video games UX

Hi, thank you for taking the time to visit this website. I am currently finishing a Master's degree in User Experience for video games at the CNAM-ENJMIN. My current degree has allowed me to further my knowledge of video game development, while providing me with first-hand experience in UX applied to games through several team projects.

Prior to this Master's degree, I have had the opportunity to study Project Management and Game and Level Design. These degrees have provided me with a broad set of skills, and have helped me understand the constraints of all the professions involved in video game making.
I was also able to apply my skills in a professional setting, by working as a Localisation Tester at Electronic Arts Madrid, and as a QA Intern at Kolibree, a French healthcare start-up partnered with Colgate.

What Have We Done To Each Other?

What Have We Done To Each Other? is a project I worked on with a team of 10 over 4 months. In this narrative game designed for PS5, the player alternatively controls 3 siblings as they try to find the truth about their cousin's death 15 years ago.
As the UX Designer on this project, I worked on the design of the UI in Figma and Photoshop, made benchmarks and guideline documents to assist designers, artists and programmers, and organized several user tests.

Junkraft is a top-down shoot 'em up made with a team of 9 between mid-December 2018 and January 2019. My role within the team was focused around UX and UI. I made a wireframe of the menus for the game using Adobe Xd, and created assets for all the buttons in Photoshop. I also helped in gathering player feedback, particularly focusing on the user's understanding of the game mechanics and the difficulty level.
