Yes. I used it for Petoink last year and I was really a newbie with the engine. Very user friendly IMO, if you're a programmer I doubt you'll find it hard to use, gdscript is fine, else you can use c# with mono (except that there is no web/mobile export for now).
The general concept of nodes and scenes and their organization is what gave me the most confusion at first..
Using it again this year of course.
