☢️ MAJOR UPDATE 1.1.0 - Play Unstable Nuclear Reactor 🚀

For the past seven months, I’ve been working on this project completely solo. During development, I conducted extensive playtesting with over 10,000 players across various WebGL platforms to refine the core gameplay.

WHAT CHANGED?

Based on tough feedback regarding harsh RNG and a lack of tutorials, I reworked the core experience by introducing:

  1. Hold Slots: Store up to 5 atoms or tools to use when needed. If you need to clear space, you can discard an item by spending a few Radioactive Coins.

  2. Equip / Unequip Tools: Gain full control over your loadout by toggling unlocked tools on or off during gameplay.

Additionally, I implemented better tutorials, improved the upgrade system UI, and fixed several bugs!

🚀 A Huge Thank You!

We recently crossed 500+ wishlists, which is an incredible milestone for this solo developer journey. Your support, clicks, and hype keep this reactor running!
