Hey Dnilo,
I'm a hobbyist Game Developer looking to get into the industry in a few years. My Itch.io page (https://addisonshuppy.itch.io/ ) Shows some of the things I worked on while in school (multiple of which were pixel-art games, although the artwork was not as good as these portfolio pieces), and since school I've been working on adding networked multiplayer to my largest game yet, Super Totally Ultimate Dad Showdown https://store.steampowered.com/app/1570730/Super_Totally_Ultimate_Dad_Showdown/. Since I'm about to finish that project, I'm looking for a new one. Most of my experience is in Unity, but I have also worked on multiple projects in Unreal Engine, and one in GameMaker Studio. I'd love to work on the kind of project you describe, the only thing I require is that there is the opportunity for a flexible work schedule (As I'm currently employed full time doing Cybersecurity) and the promise of seeing the project through to completion and rev sharing (or just getting paid in general).
I'm interested to learn more about this, and do please keep me in touch!
Addison
