An incremental hex-puzzle roguelite game where merging atomic elements prevents a nuclear meltdown.

In this tactical hex-grid puzzle roguelite, you are the architect of an unstable nuclear reactor. Strategically merge elements from the periodic table—starting with Hydrogen—to generate Radioactive Coins and power your facility.Every placement matters. Use your earnings to purchase permanent upgrades and stabilize the reaction, but be careful: as the density increases, so does the volatility. Balance growth with safety to achieve the ultimate high score before the reactor reaches critical point.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4644400/extras/82924cb0bfe3ae21fd5be8e4083e90ae.avif?t=1779480556" width=780 height=500 />
