Cosmocat and Studio VDS present: Astral Flux! Two would-be astronauts and scrappers fumble their way through space, desperately searching for a way home.

  • Travel to the far reaches of distant dimensions
  • Explore ancient alien ruins
  • Come face to face with the terrifying beauty of otherworldly creatures
  • Upgrade your skills and abilities on the way


  • Twitchy retro-inspired gameplay
  • Randomized levels: no two runs are the same
  • Modern lighting and post-processing
  • Original soundtrack and sound design by contemporary electronic composer Snug

Who is this game for?

Astral Flux was designed for players seeking a moderate challenge. There are no checkpoints and death is permanent, so learning the mechanics, enemies patterns, etc. is key to progressing. For most players, we expect this will take between 2 and 5 hours.

The game features some roguelike/lite elements, such as procedurally generated levels and permadeath, but this is not a full roguelike. There is currently one main game progress route, and no meta-progression, thus you can expect an experience similar to a challenging action platformer.

This game is great but it is stuttery and slow on my
Geforce 8400M GS Vostro 2510 laptop.
I have tried with vsync on and off as well as in lower resolutions but it makes no difference.
I realize the laptop is old but this game shouldn't need
high end specs. I run other 2D games like Axiom
Verge, Shovel Knight + SK Dig, Astalon, Alwa's
Adventure & Alwa's Legacy, Cyber Shadow, Chasm,
Dolphin emulator and many more fine.
Maybe you could add some options to turn off some graphic features (lighting, etc.?) in future builds?
That would rock! I love playing games like this in bed on my laptop. It runs great of course on my gaming system in the living room which has 16 gigs RAM, a GTX 1060 6GB and an I5 quad core but I tend to prefer smaller 2D games like this anyhow.
A Linux build would rock too!

Hey MENTD, we recommend a mid-range PC due to the 2D lighting, post-processing, etc. That said, we will be looking at making some optimizations in a future update, as well as adding a few quality options, so stay tuned!

I do have a pretty kick ass PC - an i5-3470 QUAD CORE @ 3.20 GHz per core with 16 GIGS of RAM and an NVIDIA GTX 1060.
It runs the game great! However, I also have a laptop which has the GeForce 8400M GS and I really love it for gaming in bed.
It is nice to have all the features cranked to high on my big gaming PC in the front room hooked to my big screen HDTV and using my bluetooth connected PS DUALSHOCK controllers,
but it's also nice to be able to play on my laptop while in bed
using the keyboard and, if needed, the option to turn off or
reduce some of the graphic features so that the game runs
better. 8)


Please also upload your early access build to Steam. Id love to consolidate all my EA stuff in one place

Steam keys are now available for anyone who's bought the game on itch
