A downloadable game for Windows

Download NowName your own price

Marble Marcher is entirely ray-marched (similar to ray-tracing) in real time and is played on the surface of evolving fractals.  The goal is to get your marble to the goal as quickly as possible.  There are 24 unique levels to master.


This game is the result of a fractal physics engine I developed that allows fast collisions with fractals and other procedurally rendered objects.  As far as I'm aware, it is the first game to ever use this technique.

The game is also open source: https://github.com/HackerPoet/MarbleMarcher

The game is no longer in active development.  However, due to the open source nature of the project, further development can be found with "Marble Marcher Community Edition" which can be downloaded here and has many new features: https://michaelmoroz.itch.io/mmce

System Requirements

You will almost certainly need a dedicated GPU to run this game at 60fps without lag.  Older GPUs may need to run at the lowest resolutions, while high-end ones can run fine at the higher resolutions.

Is it a virus?

Marble Madness and Super Monkey Ball took acid and had a baby.

This game is cool.


10/10 couldn't work on my world geography final because of this game. would recommend.


* sad mac user noises*


You can just build it yourself on any OS:


If we could disable shadows it would probably be able to run easily on about any hardware. I run on the second lowest setting on intel HD Graphics 620, and it's butter smooth on scren saver (50-60 fps), and between 30 and 40 fps when playing. Maybe an opaque marble could save a few resources for lower-end devices too.

As for the gameplay and the music : simple and nice.

We have potato?

Potato changes the resolution for rendering everything, with an insanely low 320x180 (I don't know who would actually play like this). It does run smoothly on low-end GPUs but is nowhere near looking like enjoyable.

Adding settings for shadows (which can be very power expensive) and reflections (same goes) would allow for higher quality rendering but better performance on every hardware, including low-end, perhaps drastically.


I use the potato setting...


i also potato!


CodeParade Made a video about the rendering process and(according to him) due to the way ray marching works
Shadows come at pretty much no extra work when rendering


I love the catwalk and the sponge, keep up the great work


interesting... trippy kinda feel or something. Really cool looking art!


noice, a game that features fractals. Kinda wanna try


marble marcher for mac is gone! crabrave?

no. this is a serious problem.


im on mac too


It looks amazing


Anyone else had to learn the hard way that right click resets? That made me feel literal pain.

omg yessssssssssssssssss


i cant jump


that is not possible. You can jump by going over ramps


Or over bumps so tiny they don't even fill a pixel on the screen lol


try to make it for crome if posable

Are you talking about a Chrome Book? When yes you can just enable linux mode and recompile it.

what is linux mode

It's a 2016 chromebook it's not the one 2here can do the roof style

https://support.google.com/chromebook/answer/9145439?hl=en That

can you give me some step by step intructions on how to load it through linux

(1 edit) (+1)

When hhaving that activated you have an app folder called Linux in that there is a terminal. That will you need. In the terminal you need to download the source code. Run in the terminal "sudo apt install git libeigen3-dev libsfml-dev make cmake" to install the dependencies. Now run "git clone https://github.com/HackerPoet/MarbleMarcher" to clone the git repo. Then "cd MarbleMarcher" to open that folder and then execute "mkdir build && cd build" to create a new folder and open it "cmake .." to setup the build system "cd .." to get back to the root folder "cmake --build build" to build it

wish he had support for other platforms. looks interesting.

Which platform do you use?

i personally use linux


Well, you can build it yourself. It's open source…. I myself use linux and tried it

(1 edit)

how do i do that? (nvm)

How do I fly or just explore?


i want this open for mac, please. please.


It is, you just need to build it yourself


Hello! First of all, congrats on the great work, really interesting. That being said, have you written any papers, tech reports or material that can be used to study the theories involved and your application of them in making the game?

I ask that because I am a university teacher here in Brasil and I currently have a student working on procedural generation of game scenarios and he has found your game and now he is very interested in doing something similar.

Thanks in advance!

I have not written any papers on the collision detection used in the game (my main contribution here).  However, there are many papers and tutorials already about ray marching rendering and procedural fractals or terrains.  Specifically, you could check out the work of Inigo Quilez.  But for collisions, I do have a more robust implementation in my python framework PySpace that generalizes the NP function to other SDFs besides Marble Marcher.

Thank you again for the quick response! I'll make sure to check the reference you provided as well as your python framework.

Now with the release of the RTX 3000 cards, do you plan on adding a 4K patch?


most likely there won't be an update for that but you can take a look at the Marble Marcher Community Edition, that has support for custom resolutions and also has better graphics and performance.

Hope all work is good for hyperbolica . So, I watch your garfeild video and thought about you making something with a similar tecnology, but with random shapes for each picture.If you make something like this, thank you and have a great day.

Thank you!

running it under wine works pretty well!

I had this bookmarked for the longest time.
Finally tried it, and it's great!

this is a good start for a first game!


cool game i sugest mmce for more levels

it says failed to complete vertex shader pls help


Maybe make a mac version?

You can run it on Mac if you follow steps here: https://github.com/HackerPoet/MarbleMarcher

the last level is very difficult, took 20 mins to figure out the path

(2 edits)

It's runs in exactly 30-60 FPS (does vertical sync is turned on? Hate it; without vert sync it's about 40 FPS) on 2k with GTX1080. Can you add 3840x2160 option?

Good game. Would be nice to have checkpoints and jump button

you could try to run the Marble Marcher Community Edition on that resolution, that also has better performance and graphics

How do i install


i have potato.


CAN WE GAIN THE ABILITY TO CHANGE THE CONTROLS?!! I'm left handed and instead of moving with WASD, I use IJKL, but this game forces me to play with WASD.

(1 edit) (+1)

You can change the the two lines  Here by replacing

Keyboard::A with Keyboard::I and so on with desired keys to change the controls then compile.

fractals can be generated randomly by the computer , it was better if the levels of the game were generated randomly by the computer to make the game become endless , 

watch his video on you tube. there he explains why this doesnt work. the distance estimator is not good enough for most fractals. thats why he had to handselect them.

(2 edits)

I would like to see the option anyway. You can put a notice before it that says something like, "Untested fractals might be buggy. Gameplay consistency not guaranteed."

There is a game called Superflight that does something like this. It has what it calls "seeds" which are basically input variables to create the procedurally generated world. Then people can share their favorite "seeds" and the game creates the same world to play around in.

With this method, even though many fractals won't work, people will find and share the ones that do.

By the way, this project/game is fantastic and I would like to support Marble Marcher in any way you need.

(1 edit)

that is actually a great idea. can you please tell him about it.

you can reach him over email


or over twitter


I'm not actively developing Marble Marcher right now, but the community edition is, that would be a better place to request new features: https://michaelmoroz.itch.io/mmce

-i have potato.
--i feel you'r pain bro

-the distance estimator is not good enough for most fractals. 
--I fix collision so now it works on all fractals that I try / create
at some lvls its even colide with micro pixels(invisible from big scale)

-fractals can be generated randomly by the computer 
--they can, but they are not fun – at many cases they looks similar and ugly,
its like generating music from random notes..

it more looks that you want: long trip by fractal that smoothly changed 
yes – it looks fun
but its hand crafted lvl / with list of acceptable fractals that may be randomly slightly mutated
, but its totally different game mechanics – not so easy to develop 

Mouse acceleration on the camera makes navigating later levels a lot more painful then it really needs to be. There should really be an option to turn it off.

I like it, but I would like it even more if the marble weren't so weighty and had more mid-air control, and the niche of the visuals weren't so restricted to the visuals. Maybe give an item/boost that lets you change the environment temporarily or speed up/slow down its change.


failed to compile vertex shader...


is there a mac version?


you can probably compile it on a mac


what does that mean?

It means take the source code and execute it directly which is framework independant. It's explained how to do in the readme file : https://github.com/HackerPoet/MarbleMarcher


really so good!


You have created something which will dictate the future of videogames. You're a genius
