1:11:52roflraging When doing exploratory / experimental programming, I find it difficult to decide between seeing things through or switching to a different approach. There have been many times where I start off on a path and things are going great, but eventually I stall due to some unforeseen problem. Often, I spend a crazy amount of time thinking about how to solve / get around the problem, even in simple ways. Analysis paralysis if you will. Any suggestions? Literally, just keep on writing code, no matter how dumb it is?

1:26:41starchypancakes What would you think about adapting the art style to be easier to implement, either at all or this early on. The trite example being for the sword collision you mentioned early on, what if you were to do something like: okay, the sword is going to teleport along the path instantly in one frame and some red line a bit like anime that would be persistent through a couple frames. Basically potentially fundamentally changing the art style with the purpose of getting things to run better. Are there any examples of something like this occurring that you might have heard of?

1:28:54jackkrozzer You always talk about the ways of programming when you started or when programming was at its prime. How can I, an 18 year old, know what it's like or get the knowledge you have about programming? Are there any books or languages or SOMETHING I can do to learn the old ways of programming? [see Resources]
