And I liked it, liked it more than basic Python, etc. A couple of months ago, I started writing my own OS, I decided to name it after my cat Marfa — this is my first major project! Don't judge me harshly! hahaha</p> <p>Briefly about the version, the first version has been released:<br> There are: driver check logs, a logo, a shell, and 13 commands.<br> There is multitasking based on timer ticks.<br> A snake game<br> FSOD (similar to BSOD)</p> <p>I would like to hear criticism and suggestions on what to work on next!</p> <p>Thank you!</p> <div class="ltag-github-readme-tag"> <div class="readme-overview"> <h2> <img src="https://assets.dev.to/assets/github-logo-5a155e1f9a670af7944dd5e12375bc76ed542ea80224905ecaf878b9157cdefc.svg" alt="GitHub logo"> <a href="https://github.com/d0ct0rvrach" rel="noopener noreferrer"> d0ct0rvrach </a> / <a href="https://github.com/d0ct0rvrach/Marf-_it_Teh-MIT" rel="noopener noreferrer"> Marf-_it_Teh-MIT </a> </h2> <h3> </h3> </div> <div class="ltag-github-body"> <div id="readme" class="md"><div class="markdown-heading"> <h1 class="heading-element">MarfaOS V1.0</h1> </div> <p>Hey everyone!
