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.
About
Star Stuff is deceptively cute programming puzzle game for curious minds of all kinds. Join Mija, a brand-new star engineer, as they take on over 150 mind-bending factory puzzles.

Looks cute, right? Making stars isn’t as easy as you might think, but you aren’t alone! Your work in the factory is supported by a variety of bots with many different capabilities. Some bots are able to lift heavy objects, and some can solve complex problems with lasers - which is a pretty enviable skill. Just make sure you keep your goggles on.

Once you’ve programmed your bots, join in on the manual labor fun! Unlike most automation and programming games, you have to work in sync with your bots from time to time. It’s a team effort here at the Star Stuff factory in order to get those stars made. If at first you don’t succeed, brush off that stardust and try, try again.

The star factory is extremely forgiving and you won’t even get fired. You can always reset, undo, and try puzzles over and over again. You can take breaks in this whimsical atmosphere with a stellar soundtrack. And remember, it’s only been 32,767 rotations since the last major incident. You can help maintain that record!
Exercise your brain. Automating bots is tricky, despite their whimsical appearances. Every problem is a chance to learn something new.
Over 150 celestial levels to tease your brain with even when you’re on your mandated lunch break.
You are part of the puzzles! Your bots can’t do this on their own - you have to pitch in sometimes to help the machines solve the obstacles they face in the star-making process.
Simple but deep mechanics make this title accessible and family-friendly. Try playing along with a friend or family member nearby!
Unleash your creativity as you delve into coding logic to craft your own bot programs. And don’t worry! Programming is just puzzle solving at the end of the day.
There’s a whole cosmic universe out there waiting to be built if you’re up for the challenge. Shine on!

Best Programming Puzzle Game = Star Stuff
Great puzzle game. It's on the easier side, as the solution space tends to be quite small, but some puzzles are very satisfying to figure out. Runs well on Steam Deck too.
I’m really enjoying the game so far. The puzzles are well-designed—challenging enough to keep you thinking, but not frustrating. The dialogue didn’t really grab me, so I ended up skipping most of it. It’s not terrible, just not that interesting to read. Two things that took away some of the fun for me is that the game shows you exactly how many lines of code your solution should have for each bot and it hides instructions that should not be used. It makes it a bit too easy sometimes, since it gives away too much about the solution. I would rather have a hard mode that doesn't do that. Still, if you enjoy coding-based puzzle games, it’s definitely worth playing.

Fun puzzles! Could have had a bit more difficult challenge puzzles though.

The best programming-like I've played, and the soundtrack is top-notch!
Cute, and not too hard for an old man with an ossifying brain (I did use the hint mode a fair bit, though).
Have around 5 more offline hours in steamdeck. Full of clever puzzle, and put all the mechanism in a good use. And the control is simple and work great in steam deck, very well designed for control and steamdeck.
I like the idea that it combines action-puzzle with programming elements. This can be very nice to get kids into that without make them yawn. The style and art is very cute .
Jeu simple et intuitif, seul point faible: il est court. Il y aurait la possibilité d'avoir un peu plus de niveaux si il y aurait des niveaux avec des mix de plusieurs éléments existant au jeu.
