Same! (Except I learned a lot about Godot instead of Unity). Thought I was finished last night only to find a major game breaking bug that only became apparent when I exported the game. Spent my day at work trying to think of solutions, got started on it as soon as I got home, got everything working, and submitted it a few minutes ago. Feels so good!
My game might not be the prettiest (only getting started with pixel art) or most innovative, and the code is definitely a mess, but it's working and it's also the first game I've actually completed. I've learned a ton, and it's given me confidence for tackling bigger projects in the future, so I'm really glad I did this.
