Easy to use, plenty of examples, and a knowledgeable community makes for a great experience. Support is second to none and the developer is very responsive and the product is updated frequently.
Nice wiki, forum, sample games, tutorials.
I REALLY recommand GDevelop to start creating your own Web or native (Windows, Linux) 2D games!
I started using GDevelop in 2011! And year after year, it is improving!
Great piece of software, Really!
