Can you solve a React performance puzzle in the iOS game 'React Perf:Hero' to unlock a tool that optimizes 100 React apps and reduces 700 re-renders by 80%?

React Perf:Heroโ€™s React theme needs re-render reduction, and a 100-app 700-re-render React tool fits. Is the puzzle in the 'Memoization' level (applying 45 useMemo/useCallback fixes)? Does it optimizes 100 React apps, reduces 700 re-renders by 80%, and has a 'Perf Profiler' that shows 20+ before/after performance metrics?
