One thing I learned about, and managed to use in the game, was sound effects. Not like I got as many of them into the game as I wanted, but the game is sorta playable with the eyes closed, which I wanted it to be. And I also practiced 3D modelling, but spent way too much time on a model I didn't finish in time. Well, it was my first jam game, and my third or so finished game (the others, I haven't published). It was probably more fun to make than it is to play, but I definitely want to make more games, even if just for fun like this one.
