I would like to add to my post mortem:
Looking back at my game, even though I want to take the time and redraw and re-edit some things I notice now, I have to move on.
So my advice here is to make sure you don't get caught up in a single project for too long since you only have so long to live :)
I don't mean this as a threat but as a friendly reminder lol, unless you have a giant lifelong project you're trying to do!
Another thing:
Making my game brought up insightful conversations between me and others about the topic of relationships, communication, and even motivated me to do research. I even took a class at my college about criminology and psychopaths, which was some of the best stuff I've ever learned!
When you're making a game, make sure you know the reason(s) why you're developing it. To inform? To entertain? To develop better habits for yourself? By keeping it in mind and getting distracted the least possible, you can focus and improve on that aspect more!
