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!

Difficulty : 2.5/5 (A bit Hard) Global : 4/5 (Great) Curator page : [url=https://store.steampowered.com/curator/44695991-Anokturnus/]Anokturnus[/url] In Star Stuff, you play as Mija, a recently recruited engineer working at the Popoca star factory. It's only your first day, yet the factory is in crisis and it's up to you to fix everything using your programming skills. Everything in this game is made to be as approchable as possible. The cute and clean visuals, the music, the soothing atmosphere (yes the factory is in crisis, but a relaxing one it seems), the basic programming... And that's usually not a good sign for me as it probably means the difficulty will be ridiculously low. I mean, a cute game with basic programming can't possibly be challenging, right? Right...? The goal of each puzzle is to reach the button at the end, using the help of various robots and mechanisms. The first thing you do when you enter a level is to go to the terminal, this is where you write the code for the robots. Well, you don't need to write anything as the commands are all listed and you just need to drag and drop what you want, then specify the targets; it's very easy to use and convenient. The number of commands each robot can receive are limited, everything needs to be optimized. Once you've written your code, you run it and the robots will start following their commands... then it's Mija's turn. Of course, programming robots in not enough to solve the puzzles, YOU are also part of it. That means the game is kind of heavy in action and timings, however it's never unfair and you can even rewind if you make a mistake. Star Stuff shines thanks to that contrast between writing code and actually interfering with it. This allows the game to combine easy programming with classic puzzle solving, resulting in a fresh and very interesting experience. The game loves to play with "eureka moments"; they won't always blow your mind of course, but that's the type of puzzle design I like a lot. More robots and commands are introduced as you progress, yet the game never strays from its simple approach. It only gets harder by being smarter, the most difficult puzzles often even only have a few commands required. Speaking of difficulty, Star Stuff doesn't forget people who want more challenge, each area has bonus puzzles designed to be trickier. I even got stuck for a long time on two of them in the last chapter, which is something I absolutely didn't see coming. The only complaint I could make is that there is no level editor. I'm sure there are more things to do with the current mechanics, and like every other aspect of the game, even creating Star Stuff puzzles seems approachable. ... I also just want more. Whether you're into programming or not, whether you like easy or challenging puzzles, whether you're a child or not... it doesn't matter. Star Stuff satisfies everyone and does it very well, which is really not an easy feat for a puzzle game. Great game, highly recommended.

If you like logic puzzle games this is a great game. Probably on the easier side--kid level stuff. The polish on this game is superb an excellent execution on a logic puzzle game. However I bought this game based on the marketing "...deceptively cute programming puzzle game." All coding puzzle/problem games have to balance coding simulation vs "gaminess." If you lean too much into the simulation side, your game becomes Computer Science homework while if you lean too much into game, it becomes a pure puzzle game. Star Stuff coding is too simplistic to learn from. Even in the higher levels, you have max three lines of code to work with. Thus Star stuff is programming flavored, rather than a programming puzzle game. if you like puzzle games this an excellent game and I wholeheartedly recommend this game. If you want to an entry level coding puzzle game, Conge's Crunch Time and Frood Robotics are a better fit.
Quick Description: -Star Stuff is a very fun and clever logic puzzler that mixes two parts charm and one part programming language to great effect. Don't be intimidated by the programming components of this game. This is a fantastic puzzler that anyone can enjoy. Whether you are fluent in Java or have no interest in coding, you will have no problem learning the mechanics and solving some really fun puzzles in this cute and colorful puzzler. Consensus: -Solid Game (Tier 3 and makes up 35% of my reviews). I really enjoyed my time w/ Star Stuff. I found about 50% of the puzzles to be easy, about 45% of the puzzles to be intermediate, and about 5% of the puzzles were tough head-scratchers. The only thing really holding this game back from competing w/ the best in the genre, would be a lack of really challenging or innovative mechanics. This is a very minor criticism in an otherwise really well made and fun Indie gem.
ボットのプログラミングと自機操作により各面のゴールを目指すパズルゲーム。 通常面全クリアまでで11時間ほど。 行数や使えるコマンドに制限があるので、クリエイティブな解法を導き出すプログラミングパズルというよりもタイトなデザインのロジックパズル寄りのプレイフィール。 簡単そうに見えて一筋縄ではいかない良問が詰まった、万人に勧めやすい一作。
What a cute and unique little puzzler! I had a blast all the way through Star Stuff, and I'm really impressed with how accessible it is through the level design and gradual building of concepts. There were lots of little clever moments, and some of the challenge levels were quite decent brain teasers. Star Stuff bills itself as a programming game, but I think it fits into its own niche. The game will gently guide you through concepts like looping, conditionals, and variable scope, but it has enough of its own to spin to really distance itself from other programming based games. In addition to setting up little scripts for the bots in the level, you take action yourself. This means that you are automating with gaps that you fill in through your own actions. That both changes the nature of the logic in the puzzles and adds something of a timing element to the game, albeit very generous with the inclusion of rewind and fast forward. Moreover, the commands you have for each puzzle are very limited, both in availability and the number a robot can be programmed with. Later in the game, some puzzles even require issuing commands that will fail. All of these aspects really push this into feeling more like its own type of logic puzzler than a programming game. That's not to say any of this is bad -- I love this game for how unique it is! I really appreciated the silly story about preventing a supernova in a star factory along with the cute graphics and chill music. Mija's little dance and victory fanfare at the end of each level were spot on. It's just a well produced, cozy game. I full cleared the game's ~150 puzzles, with about 1/4 of them being optional challenge stages, in around 13.5 hours without using the hint system. I found that to be a perfect length, though I wouldn't have minded a couple more of the more challenging puzzles at the end!
カジュアルゲームの幸福とパズルゲームとしての満足を両立してしまった奇跡のゲーム!
hands down the best programming puzzles game ever made. It has a perfect pace introducing new commands and concepts all wrapped in masterfully polished graphics and controls making the gameplay enjoyable throughout. The puzzles difficulty varies and it is always satisfying when you figure out the solution and see it play out.
The casual destruction I rain on these bots is crazy. Those bots *really* need a union. Fun and clever (but simple) programming puzzle game.
NB: This isn't really a game about programming at all; it just uses programming as a theme to establish a unique set of logic puzzles. It has really well-designed puzzles that provide a lot of satisfying "eureka" moments. None of the solutions feel hacky or cheesy. The setting, music and visuals are very cute too.
ボタンを押す、ボックスを運ぶといったフィールドパズルに プログラミングの要素を追加したアクションパズルゲーム。 たとえば「自分では渡れない向こう岸のボックスをボットに運ばせ、 逆にボット側で操作が出来ないスイッチを自分がタイミングよく押す」と ボットのプログラム(指令コマンドの組み合わせ)と自分の動きを 上手く組み合わせないとクリアできない点が新鮮。 プログラミングと言っても出来る指令は単純なので専門知識が無くともOK。 プログラミング概念を遊んで学べる教材としても使えそうなタイトル。 キャラクターや世界観が可愛らしく、日本語対応な点も良ポイント。
