Community Features: Leaderboards, shared runs and community uploads. Stripe integration for premium features.

Live product with 140 commits, 110 test files and active user feedback. Real-time synchronization between game and companion app.

SpireSense consists of two parts: a C# mod that extracts game state from Slay the Spire 2, and a Next.js web app that analyzes this data. The app offers card analysis, deck tracking, run statistics and an AI coach. Users can share their runs with the community and unlock premium features via Stripe.
