Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 30 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Criticality is a casual incremental clicker game about splitting atoms and creating chain reactions.
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.
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).

Fun game! (Ignore hours played above, it's much more than that--Steam is glitching out for me.) I like the theme, it makes a lot of sense (i.e., mapping on chain reactions in nuclear reactors to comboriffic incrementals)! I also appreciate the little bit of story in it. My only negative is that at one point it can be a touch grindy but you just have to rework things a bit and you'll get out of that state. If you are a fan of incrementals, it's worth picking this one up!
Great game. Takes a short while for buildup. Get as many skills as you can, prestige as much as you can to buy the permanent upgrades so you can tackle the later levels. The atoms are harder to split at later levels, so consider increasing the XP prestige so you can level up quicker for the Sundial project.

Fun game, it mixes active "action incremental" with classic idle mechanisms you unlock later. The pacing is quite good but feels a bit bare near the end game. The idle gameplay also max out quite early on. Still great gameplay with a nice polish and small narrative elements. Recommended!
Great game, love how polished the UI feels. Would like to see an improvement to the prestige tree having one long tree like this isn't a good feel even if it does look fantastic. As a dev I know its hard work doing stuff like this but maybe some kind of size scaling option or even if you stick with one size maybe it can be more of a grid. I would personally seperate purchased from available but it is nice that they move to the right when they are maxed. Overall enjoyable experience.
Quite a fun little incremental with a lovely theme and graphics too
good incremental game
Really neat clicker/idler with a peerless 50s atomica aesthetic and fantastically addictive gameplay loops. Just when you think you've got the best of its gargantuan upgrade tree, it up's and does something interesting, making it a whole new fun over again
Good game
Good early game for an incremental but drags on too long for the ending. You can upgrade the full tech tree before you get the third ending, and it just becomes a waiting game of prestiging repeatedly until you finally have just enough.
엔딩이 좀 허무하긴 한데 꽤괜 초반에는 플레이 하는 법도 모르겠고 이게 뭔가 싶었는데 환생 몇 번 하니까 토도도도독 미친듯이 연계로 터지는 맛이 상당합니다 단점이 있다면 엔딩이 너무 허무해서 엔딩인지도 모르겠다는 점 이게 엔딩임?? 더 있는거 아님?? 하다가 시간만 날렸읍니다 재밌지만 결국 게임 내 요소가 적다는 점에서 8천원이라는 가격도 다소 흠이네요
