Description

Criticality is a casual incremental clicker game about splitting atoms and creating chain reactions.

Click. Split. React. Dominate the chain reaction in a casual incremental blast of cold-war chaos! 

You’re a hapless engineer caught dead-center in Cold War politics, stuck with a rickety reactor and a whole lot of very volatile atoms. No fancy degrees or top-secret training, just your screwdriver, a dream, and a ticking clock of bizarre, high-stakes situations.

Here’s how you go nuclear (without blowing up the lab… probably):

  • Click to Unleash Neutrons - Tap to fire a single neutron, watch atoms absorb, split, and detonate in a cascading chain reaction. The longer the chain, the bigger the points haul, simple as that (until the atoms start getting tricky).

  • Upgrade your reactor, Unlock Chaos - Spend your hard-earned points for game-changing upgrades that supercharge your reactor. Unlock new mechanics, boost neutron output, and turn tiny fizzles into earth-shaking blasts that rack up points faster than you can say “critical mass.”

  • Chase the Ultimate Reaction - Push your reactor to its breaking point, hit critical mass, and reap the rewards… if you don’t accidentally trigger a meltdown first. Every click brings you closer to nuclear glory (or a very awkward conversation with your supervisor).

Go Criticality now – and remember: when brute force isn't working, you're not using enough of it!

          100% achievements in ~3 hours (could be less if utilizing offline gains)

          The skill tree not costing different amount of resources but skill points is absolutely great
          Keeping the view after prestige for cheap is also great

          Gameplay loop is fun, prestige is impactful, skill tree is well balanced and interesting
          Some achievements also require some intent to get which adds to the game
          Rocket lab is a little meh but overall great game
