Packt's discount offer for the Stencyl book has ended, so here's an offer from me... My Stencyl Game Development video course on Udemy is on offer for $15 (normally $99!) until the end of December 2015.
There are more than 7 hours of video tutorials, and there are currently almost 500 students enrolled. There's a 30 day money-back guarantee, so you have nothing to lose!
