Women Game Jam Chile · Aug–Sep 2024 · Team project
No es 18, todavía…
My first video game: a horror game with a time loop, made in Unreal Engine with a team. My computer couldn't run Unreal, so my part was in the storytelling, the project architecture (set up on a teammate's computer) and defining the low-poly visual style, including the idea of a loop where the 18 never arrives.
A gift app built as my UX-UI course project: research, Design Thinking, personas, card sorting, usability testing and components organized with Atomic Design in Figma.
