Metropolis. Atlantis. Resistance.
Will you take revenge for the unethical simulation of an inferior universe? Will you support the cruel experiments to win total control over metempsychosis? Or will you join the underground civilization that awaits the end of war in this dangerous afterlife reality?

- When I was 13, my only wish was to have my own MMORPG.
- This is when I picked up my first programming book, Symfonia C++ by Jerzy Grębosz.
- I'm completely self-taught, though I did enroll at the top3 high school in the country (at the time).
- I began writing Hypersomnia once I turned 18. I'm now 28.
- At 19 I went to work as a junior C++ programmer instead of going for a higher education.
- I later went on multiple year-long breaks from work to focus on writing Hypersomnia, whilst living from my savings.
- Since 2020, I became passionate about investing, thanks to which my savings lasted way longer than they'd otherwise.
- My financial decisions now let me focus 100% on Hypersomnia.
- I use Arch Linux, and I wrote Hypersomnia in NeoVim, without autocomplete (but with 21 other plugins - vim-easymotion being my favourite).
