These are amazing tips! Unfortunately, I didn't follow tip 2. I've spent pretty much the entire week working on my game full time (when I'm not working on my thesis) and I haven't had much sleep. But I've been having so much fun and I'm so happy with my project that I don't regret working on it.
This might be one of the best things I've created in my life! You have no idea of how happy I am! Can't wait to finish it and share with the world haha. And I also can't wait to play the other submissions, which I'm sure are going to be amazing!
