We built projects focused on puzzle games with custom characters included. The challenge was to construct the entire platform using JSON from the backend, making an end-to-end configurable game quite complex. With score calculations, character interactions, and game options all driven from the backend, error handling had to be absolutely flawless. After each session, all game data needed to be sent back to the backend for analysis. Despite the complexity, the Jash team did an exceptional job delivering the complete solution end to end. They were incredibly patient in catering to every quality requirement I had.
