• After 1 Year of Solo Development… ZK1L4 Is Finally Here 🧟‍♂️ - 16 October 2025

  Hey everyone 👋After a full year of solo development, I can finally say it:ZK1L4 is out now on Steam! 🎉This project means a lot to me. I built it during late nights after work, and even through the uncertainty of being laid off. There were moments when I could’ve stopped, gone out, rested, or waited for “a better time”, but instead, I chose to stay home, focus, and keep building.Every pixel, sound, and mechanic became part of a personal mission: to prove to myself that I could bring a full game to life, no matter how long or hard it got.ZK1L4 is my love letter to post-apocalyptic survival games, a bullet heaven where chaos turns into flow, and small victories feel huge.
