I really enjoyed godot. Once I "got" some of the concepts, I became very fast in creating elements and changing them. And I used GDScript.

When I built the first prototype[0] I also used the opportunity to try out godot. I like it a lot. It's main concept (scene <==> node) felt really elegant.

Some other engines might have better features. But One Way Dungeon is a 2D game with no real-time gameplay or physics or networking... So ease of use is more important than high-end capabilities.
