Perhaps more practical than your average tutorial, in that the resulting project helps you turn an old smartphone into a TV-style remote. (Disclaimer: I wrote this article.)
Maybe I was way off the first time I read it, but I could have sworn that Stephen Hawking's "Black Holes and Baby Universes" already claimed, decades ago, that the universe looped like that.
If I remember right, there was some analogy likening us to ants crawling on the surface of the Earth, but I could be conflating it with something else.
This reminds me of something written on an old mug: "If builders built buildings the way programmers program programs, the first woodpecker to come along would destroy civilization."
Not sure of the specifics in the last 18 months on straight OpenFL, but I know that some frameworks built on top of it had nice features like hot reloading. HaxeFlixel has an in-game debugger, too, for example. I guess it depends on the types of tooling you had in mind.
I wonder, did you have the "dead code elimination" feature enabled? (Just throwing it out there. I haven't tried transpiling to PHP with it myself. :) )
For sure--see the examples of FontStruct, TiVo, DAZN, Heidi, etc. in the article, along with the part just before the quick start section. :) (It's true, it does have a large gamedev following, but it's actually quite versatile.)
