Our work focused on enhancing multiplayer reliability, player lifecycle management, and framework compatibility. We introduced support for modern React versions, implemented new room-leaving capabilities (the leaveRoom function), improved player reconnection and state preservation flows, refined joystick input handling, and contributed supporting documentation to help developers adopt the new features quickly. While a relatively short engagement, the project directly impacted the day-to-day experience of PlayroomKit developers within Little Umbrella and outside of it, strengthening the SDK's foundation and helping make multiplayer game development more predictable, resilient, and enjoyable. ## Client and Testimonial Context - Client: Playroom Inc - Client website: https://joinplayroom.com - Client territory: California - Client short bio: The lightweight multiplayer backend which powers hundreds of games. - Testimonial author: Tabish Ahmed - Testimonial author designation: CEO - Testimonial company: Playroom - Testimonial: The Grayhat team have been an indispensable asset to our startup journey at Playroom.
