Found this tutorial by a user the easiest to get into, in programming with it for the first time
It shows the tutorial in flash with the game at the end of the tute, so even if you're just curious you can load it up to see how it ends.
It's slightly out of date with newer versions of Stencyl, but I managed to muddle through. So if you have trouble post a comment since I was able to get through it I might be able to help you do the same.
Anyway, I kind of want the flash capability but at the same time if it's more of a struggle than using Unity is, then I dunno about pressing on with it.
