Oh yeah I highly recommend Godot. I migrated from Unity to Godot when Unity got a bit controversial with their pricing plans. That's when I decided to go fully open source :-)
The nice thing is that Godot is much lightweighter. With Unity I was annoyed you have to always look at a loading screen, while Godot is very fast. And once you understand that all scenes are also prefabs, you should be good to go. Then it's just about learning all of the basic nodes.
There's some stuff I do miss from Unity: Like having multiple scripts per object, but you do get used to it. GDScript is also quite easy to learn.
I would say: Give it a try. Especially for 2D or 2.5D games :-)
