Hello everyone,

For the past 7 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.

# ABOUT THE GAME

Unstable Nuclear Reactor is an incremental hex-puzzle roguelite game where you merge atoms into higher elements, trigger massive chain combos, earn radioactive coins, and manage your ring capacity to survive as long as possible.

# 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!

# WISHLIST & PLAY THE DEMO

I really need all kinds of feedback, as I’ll be entering Steam Next Fest with 500+ wishlists. Please give the demo a try and help me identify anything that could be improved or fixed.
