I'm done!
I spent the first 36 hours repeatedly rewriting my game because physics is hard, but I've managed to ship my first game jam game ever! It's not what I was planning on but it feels relatively complete, and it was a lot of fun to build everything from scratch in 3 days.
It was particularly fun to write a little bit of music since I like to play piano but had never made electronic music before :D
Do I need to do anything to mark my game as "published" or does that just happen when I make a game and select "JAM" ?
