In previous jams I kind of said, I'll make a platformer that I've already done a tutorial on and then I'll change this and this to make it different. This time I was just kind of, I'll make a game that does this, and to do that I'll need these features. So I don't think any of what I'm doing is new (although I'm so out of practice I'm having to do lots of research anyway) but I'm putting them together in a new (for me) way, which I'm pleased about. It makes me feel like I'm progressing a little.
