What kind of game is Flux Caves?

Flux Caves is a 3D puzzle game. My plan is to create something which can be a challenge, but still you enjoy to play. I want to create a soothing environment and this is enhanced by slow piano-based music. Big inspirations came from the Witness and from Zelda: Breath of the Wild dungeons, Sokoban and the classic Pipe games.

The actual development version game now contains:

  • 9 cave level
  • 3 open world puzzle
  • The gameplay is around 25 minutes now

The plan is to create around 50 levels, and after that a level editor.

Recommended system requirements:

  • CPU: Intel i5 8400 or similar
  • RAM: 8Gb
  • VGA: 2Gb VRAM (AMD or Nvidia)

Minimum system requirements:

  • CPU: AMD A8-5600 or similar i5 
  • RAM: 8Gb 
  • VGA: Nvidia GeForce GT710 or similar

The game is unstable under 8Gb RAM or with Intel video cards!

From the looks, this reminds me of Infinifactory, if it turns out half as well I'll be happy. :)

I didn't play all levels ATM but here's what I have to say about the game. Sorry in advance if I make a suggestion about things that are in the part I didn't play :-) But first, nice addictive gameplay! Reminds me about Pipe Dream and Sokoban!

There could some block rotating device in harder levels.

I had some issue for pushing blocks beside each other. If we are supposed to be able to do so, maybe considering activating the push from a little further away from the blocks.

I think the player could jump the height of 1 cube. Like that, you could remove most of the stairs in the game field :-)

Maybe the ball gathering lights could be more visible. Like a screen beside the exit door, or even directly on it.

Yeah you are right, the basic mechanisms comes form Sokoban and the pipe games. I dont know why I skipped them as refference from the game description. Now I fixed it :)

The block rotating device is a good idea, I'll figure out something today. 

For pushing block besied each other, I made a reset mechanism for all puzzles. But also want to make an Undo Last step feature, but that have some problematic technical part, what I have to figure out before implementing. :)

And thank you for the comments Blitz! As soon the game have rotating platform, I'll inform you :D


Great concept fubenalvo!! Definitely unique and i'm looking forward to how far this game can potentially go if you add a level editor. I do hope that you consider creating a storybased game soon though...? Again, like the last comment, I found that the elevator made the pipe block 'hover' a little bit and had to reset the level. But that aside, the graphics and sound effects are amazing for a free indie game. You're very good at creating a 3D enviroment! Here's my play through (I think OBS struggled at some parts).


thank you! finally I found today what's the problem with the elevator.  This wasnt an easy one to figure out :D
The elevator lifts up the yellow when the block is on the edge, and the elevator come up after that. So nooow I can fix it.  this is the real beauty of game development :D

The second open-world puzzle doesn't work for me. One of the block seems to be floating a bit above the ground. (Probably caused by the elevator)

Also when I move a block on the elevator, while the elevator is moving upwards, the block disappears in the ground.


Which block making this, the orange crystal block or the pipe one? 
I'll check this, thank you for the feedback! ;)

I saw that you've fixed it in the comment above, but it's the pipe that goes pretty much in the middle of the whole construct. The one you need to transport with the elevator. 

Super cool game you need to publish it in steam

The long term plan is ofc the Steam release, but before that I have to do a lot. I mean more level, hidden collectibles, story, but I have tons of ideas, which I hope will fit in the game too :)

Proboably the game will be on Steam in this year. I can't even say a more precise date yet, because I don't know when it's gonna be finished.

Aaand ofc I'm glad you liked it! Thank you! ;)

Had some issues with one puzzle but overall it's been a good experience. :)


Thank you for the video! I'll check the level05 for this problem. Probably there was an error when you hit the reset button, and after that everything crashed in the background. :P

(x-post from GJ)

Damn dude, wasn't expecting this after Neon.Code, but it's awesome so far! The puzzles have a good amount of complexity to them and do a great job of explaining themselves. The visual style is really cool as well, love the puzzles in-world kind of situation and it reminds me a bit of The Witness and Talos Principle. Looking forward to the later versions!


Thank you for posting it here too! And ofc as one of my favorite video makers, I'll search you when Flux is near to completr,  to create a new video maybe!? :)
