I have tried Godot, But I didnt find it anywhere close to C2
It has visual coding, but you should know C++ to do major tasks, Im a designer, not a coder (so it didn't work for me). The engine UI doesn't look solid aswell, Also limited help resources..
The closest to C2 that I found is "GDevelop" its literally like a C2 Sibling.
If you want you can try that out, its Free opensource.
