latest update


0.1.1 September 1, 2025

Karyofox 0.1.1 is out!

This update focuses on fixing up stuff based on feedback received after release. Thank you to everyone that provided their input and reported bugs! Here are the changes:
||- added a max generation selector

  • fixed an apoptosis milestone
  • updated fourth hypercell upgrade
  • attempted to fix the NaN glitch, i'm sorry if it's still an issue
  • fixed z-index of apoptosis button
  • fixed styling for genomes that can be afforded but are not connected to an already bought genome
  • made affordable genomes more apparent
  • made two more genomes permanent
  • made end-game a little clearer
  • added two options (compress stats, show max generation selector)||
    Thank you for playing, and if you encounter anymore issues, don't hesitate to let me know! Gup gup!

Good game really, however the unobtainable genomes are annoying, even tho i abused exocell upgrades the minute i got nan'd.
all great things come to an end some are in development
4/5 because the nan thing, and the genomes

-217 max generations with -1185% mitosis chance sounds bad

Beginner tip: Don't buy the max cell generation until you can get at least a 40% mitosis chance, otherwise your cell gain will actually get nerfed

Thought I was crazy till I tested it. Using same import file found that increase max amount of cells nerfs your income. Going for same total it took 3 more seconds with 1 level in max cells than without it.

developer response: unfortunately a side effect of this kind of currency gain. maybe someone else will improve on it in their own project! it becomes bearable a little later on i promise.

cell generations are crippling to economy. It takes about 16 generations for 20% mitosis to be profitable, about 9 generations for 30% to be profitable. Not really sure when it becomes worth it to start buying mitosis and generations because of the cost scaling. Probably once 100k cells can be generated in a reasonable amount of time

you should get points on every generation, not just the last generation, because right now, it takes a lot of upgrading to make buying the generations upgrade actually give you more points/s
