Hi Product Hunt! 👋 I'm the maker of MewGenius. I've been obsessing over Mewgenics (the new game by Edmund McMillen, creator of The Binding of Isaac). The game is brutal. It has permadeath, hidden stats, and opaque mechanics. I got frustrated failing "90% chance" events, so I decided to dig into the game files (classes+Misc.txt, events.csv) to see what was really happening under the hood. What I found changed everything: The game uses a hidden "Reroll System". Luck 5 is base. Luck 15 gives you 2 rolls. Luck 25 gives you 3. I built MewGenius to visualize this math. It's not a wiki—it's a Decision Engine. Key Features: 🎲 Luck Calculator: Calculate your true success probability based on the hidden reroll formulas. 🧬 Breeding Sim: Simulate genetic outcomes. It flags "Dominant" traits so you don't accidentally breed a cat with a contagious disease. 💀 Boss Guides: Tactical breakdowns of HP, range, and ability patterns. The Tech Stack: Built with Astro & React for speed, hosted on Vercel. I wrote custom Python ETL scripts to parse the raw game data into structured JSON APIs. It's free, fast, and mobile-friendly. I'd love to hear your feedback on the UX or any features you'd like to see next! Happy breeding! 🐱
