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.

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.

I mean it's cheap, but still about 4-5 hours to get all the achievements. Glad I got it on half price sale, otherwise I'd be a bit more irritated.
[i]Feed the Reactor[/i] is a [h1]perfect 5 hour incremental game.[/h1] Progression curve that [b]keeps things fresh for the entire runtime?[/b] Check. Simple but [b]surprisingly deep core mechanic?[/b] Check. "Crank" for [b]active play[/b] that speeds things up but does not feel mandatory? Check. [b]Ending that actually tests your gameplay mastery?[/b] Check. (Good endings are much rarer in the genre than they should be.) Completionist achievement that takes a bit of effort but [b]doesn't take mind-bogglingly boring grind?[/b] Check. Good writhin with [b]humour [i]and[/i] plot twists?[/b] Orteil42 would be proud. [h2]In conclusion,[/h2] you should probably buy it. Personally, I am certainly going to check out Adam Travers' other games.

At first this feels pretty standard for this genre of game, but by the end of my playtime I had an experience with this that delighted me. After getting into the hundreds of materials budget, it at some point does feel like I'm tinkering with some kind of exotic matter engine. Some later upgrades allow the particles to behave with each other in totally new ways and arrange into emergent patterns, trying to discover new chemistries to push out maximum power. At a couple points I did something by accident and just watched an interaction I hadn't thought of happen, then use that in a new setup. The story isn't anything elaborate but I found it pretty entertaining, and the thematics of the space travel manage to come through. Unexpectedly quality piece right hur
Eh? It's okay, I guess. At no point did I feel excited or like I puzzled something out. I got all achievements except for one after 2.6 hours. I only bought it because I generally enjoyed the dev's other game Journey to Incrementalia.
A fun little incremental you can complete in a day. Not a ton of super unique gameplay elements, but the visual style is somewhat unique and there's a tiny story to keep you engaged near the end. I'd recommend waiting for a tiny sale to get it at $5 and under but it's worth the $7 if you can't.
The game's short (i was afk for 1+ hour so it's less to complete; also I stayed a bit longer for all the achievements), but kinda fun. Quite an interesting core mechanic as for an... idler? Not an AFK game at all btw
A nice 4 hour game relaxing with very interesting lore. Wish there was more in the game! (lore, more systems, more creatures)
Short but good. I liked how late game added more content.
Nice idle incremental game. You can balance and focus on upgrades in several different ways and try out different things or just brute force your way by waiting long enough. The story was a bit meh but rewarding enough as a goal to motivate you towards finishing the game.
Particle go zapp and the music is fire!
