I got to chapter 33 of the course and everything went to crap. He started filming things out of order and I lost the plot :(
But that just means there's no better time to strike out on my own and get my game started; I know enough about how Unity works to get there, so now I just need to punch up a script and get some assets together. My goal's going to be a 5-10 minute demo (reasonably, without too much fast clicking through) that by the end doesn't crash on bootup. KEEPING IT REASONABLE!
