This being my first game jam, I learned that I really enjoy the spaghetti-code minigames I get to make and signed up for two mor game jams in the future :D
I read documentation about Godot nodes to change details that I never learned about in tutorials. Also I realized that playtest feedback is very valuable to catch problems of any kind and I should spend some more time in testing than I did here. And finally, I learned to engage with game feedback in a healthy way - not taking it personal and letting it affect my feelings, but instead as a way for other people to constructively make my game better!
