Niice, great interview and pretty cool to hear about the many Flash-related projects Mike's been into, especially as I'm still using Swivel!!
On a sidenote, this got me intrigued about pinball machines.
Reviews for "#12 - Mike Welsh (Creator of Ruffle/Swivel)"
I'm surprised at how young Mr. Welsh sounds. I thought that someone with so much experience/coding expertise would be older.
This interview was extremely interesting.
Also, the standalone flash player is available for Windows and OS X, unlike the Newgrounds player, which is windows only. However, ruffle is for Windows, OS X, Linux, and the web.
You can run a flash submission in Ruffle by adding "?emulate=flash" to the URL.
