OVERLOAD REACTOR

You're the reactor's last operator. Vent the charging cells for power — but let one hit critical and it overloads. Swipe to vent a whole line.
Classic shift · Endless survival.
Same board for everyone
HOW TO PLAY
Tap a cell to vent it — or swipe across same-level cells to link them. Every link pays more.
Higher charge = way more points. Grab it at MAX for a 2.5× overcharge.
Miss it and it goes critical — tap in the last instant to catch the blast.
STABILIZE purges the danger — but you only get 5 charges a run. Spend them well.
Fill the core to 80% and it's meltdown.
