About
Cozy Marbles is a comfy game about building marble runs. Using a huge range of bits and pieces from charming homes, fairytale realms and starlit spacecraft, fit together the marble course you’ve always wanted to build and play with. Unwind to a bespoke lo-fi soundtrack and roll with the nostalgia.


Tinker with freeform construction tools and a rich library of parts. Design awesome spirals, twists and drops, then roll your marbles off on their adventure. Take “playing with marbles” to a whole new level by guiding them across complex courses, bouncing over obstacles with boosters, ramps and cannons, floating dreamily through anti-gravity fields, and even making music with xylophone blocks.
Play in a range of environments with themed parts:
A mellow Living Room, in daylight or at night.
A whimsical Fairytale Tavern, the perfect place to build a castle coaster or labyrinthine mushroom forest.
A mesmerizing Space Station for high-tech futurism including portals and laser tunnels.

Build your marble run from wood, metal or plastic, choose its colors and give it a name. Customize your marbles with a range of colors, patterns, national flags, facial expressions, stylish hats and silly little arms that flail while rolling. Beat challenges to unlock even more customization options, track pieces and environments.

Cozy Marbles is a little game with a big brain. Plan and experiment with all sorts of marble constructs, from marble rollercoasters to wacky apparatus. Watch your marbles flow through carefully laid routes… or fly way off track!

Assemble a marble course, drop your marbles and watch them race to the end. Use checkpoints to split the track or set up multiple start and finish lines wherever you want. Make your race sweet and simple, or huge and complex with tons of laps and hundreds of marbles! May the best one win.

The next step after perfecting your marble masterpiece (or diabolical marble trap) is to share it with the world. Export and import courses to show off your build and try everyone else’s. If you’re a streamer, use Twitch integration to let Twitch Chat drop marbles into your course and join your race!

Perfectly scratches that "I love watching Jelles Marble Runs, but I'm certainly not talented enough to make creations like this" itch! With the sandbox provided, it feels like i can envision something i would like to make, and enough tools to create that vision! Probably helps that my vision isn't that wide in scope! Music is super chill, challenges are fun to attain (would be fun to see more added eventually too), Great set pieces and I'm sure there is more to come! Amazing work from a solo dev!
I am a 45 yo father, probably one of the oldest people playing this game. I am a single father to my Son, who is 14 now. My son got this game for Christmas in 2021 from his uncle, so we installed it on his computer and he started playing. By the end of the week he had 24 hours on this game. This was horrible for me, as it was already hard for me to find ways to spend time with my son, as he is always out with his friends or just watching YouTube. So i decided to make a Steam account and get this game to see if I could maybe play alongside him. I loaded into the game, picked my character and world and started playing but I was stuck on what you where supposed to do. I asked my Son for help and he hosted a game for me to join. I loved it as it was the best time I had spent with my Son since my wife had died. This game has ever since brought me and my son closer again and now we actually spend time together outside the house together as well. This game reminded me that there's fun to be had in everything, and it has brought both me and my Son many happy memories.

[h1] ちゃんとチルいビー玉コースターたち [/h1] プレイ時間:2.3時間 (公式ステージ+カスタムステージを色々遊んだところ) 創意工夫に富んだコースター上でビー玉をコロコロ転がすシミュレーション系ゲーム。 自由にビー玉を転がすモードとゴールを競うレースモードが存在します。レースモードはTwitch連携可能。 初期実装ステージは7個ですがSteamワークショップからたくさんダウンロードして遊ぶこともできます。 ビー玉は大量に射出することもでき最大1万発までコロコロすることができます。まさにビー玉コロコロ大作戦。 このゲームはあくまでも『理想のビー玉コースターを作り上げる』ゲーム。様々なオブジェクトをつなぎ合わせ自分の手でコースターをつくることに魅力を感じているクリエイティブな人にはとても刺さります。ただビー玉を転がして楽しみたい人は有志のプレイヤーが新しいカスタムコースターをアップロードしてくれるのを待つことになりますが、それでも一応遊べます。ループ系コースターならビー玉を動かし始めたらずっと回り続けるので観てて楽しいです(たまに詰まりますが...)。なお現時点で数十個のカスタムコースターがSteamワークショップに投稿されているので現時点でも充分楽しめます。 ※外部サービスを通じてゲームを頂きプレイしました、ありがとうございます! [code]ふぇるかです、鳥です、以上です🐦✨ Twitch([url=https://www.twitch.tv/fluffyfeluca]Main[/url]/[url=https://www.twitch.tv/felucabird]Sub[/url])/[url=https://x.com/fluffyfeluca]X(Twitter)[/url]/[url=store.steampowered.com/curator/44977063/]SteamCurator[/url][/code]
oh god oh frick one of my marbles clipped through the floor mom's gonna kill me
The course builder is easy to learn with an interface that feels detailed enough to get you used to the mechanics without it feeling overwhelming. Customising your tracks with different colour schemes as well as using your own made marbles really adds that extra touch of uniqueness to the courses, which I liked a lot! In-game challenges provide ways to earn tickets to buy new environments, playsets, track pieces, and customisable items/colours for custom marbles. This is great as it means you don’t need to pay any additional money to unlock fun new things to play around with and it encourages you to try various track ideas when building a new marble course. On top of this the twitch integration means that you can share your builds with your community and have them race one another. Whether just for a bit of fun or perhaps the winner gets a reward is up to you but it is a great stream game suitable for cozy sessions or as a nice break between your longer stream games. There’s enough packaged in here to keep people busy and satisfied and truly the only limit is your imagination. If you can think of it there’s a high chance that you can bring it to life. A fun game to play by yourself but I feel this excels when it is shared with community and friends on livestreams due to its built in Twitch functionality.
想要搭建一条轨道极其难受,轨道朝向难以观察的同时轨道之间磁力连接做的很差,非常容易连接到不知道哪里,特别是复杂的轨道莫名其妙就连接到下方的东西了,想要搭建一座墙也非常麻烦,方块极其容易连接到下方方块的侧面。 玩的难受至极。
Feels good, looks good and has a decent UI and tutorial. It's mostly sandbox, but there are a few challenges to complete. That way you can earn some tickets that let you buy new parts to build with and funny hats for your marbles. Performance is also good, even on my i7 6700k which is below the minimum spec. I did not try huge maps from the workshop tho. All pre-installed maps run fine. On the downside: building has some quirks that are somewhat annoying, but no dealbreakers so far. It's definitely worth the 9-10 bucks.
実際にこんなのを小学生の頃に作ってみたかった。 でも作れるはずもなくてピタゴラスイッチを目に焼き付けてました。 まさかこんなゲームが出るとは。 ただしアイデアは当然自分で生み出すしか無いので、やってみると意外と大変です。 私は巨大コースターを作ろうと意気込んで、中盤から手抜きになりました。 たぶんそこそこの大きさが一般人には向いてますね。
先駆者として[url=store.steampowered.com/app/1491340/Marble_World/]Marble World[/url]があるのでそちらと比較レビュー 今のところMarble Worldのカジュアル版という感じ 雑な比較をするとFactorioとSatisfactoryの建築の違いみたいなイメージ。 [list] [*]ビー玉の動きが丁寧で心地よく、chill [*]一部オブジェクトが物理演算でなく動いている風に見えるものがあるのがちょっと気になる [*]ビー玉が1球だけが通れる道はいろいろ作りやすいが、大量に流せるオブジェクトが少ないのでレースがちょっと作りにくい。(これから解放されるのかもしれないが) [*]自由度に関しては下位互換なのでもう少し自由に配置できればうれしい [/list] ビー玉を転がしたいならどっちをやっても損はないので、好きな建築方式で決めれば良いと思います。
its one of the best games in my library! i played during the playtest and skipped the demo but all my levels are still there :O
