Hey! Thank you very much for your comment. I'm glad you enjoyed the game.
As for why I use Godot 3 - it's because I code in C#, and Godot 4 can't build web games that use C#. There are also a lot of other issues regarding C# in GD4, such as inability to export C# collections, and etc.
So far, my experience with Godot 4 was underwhelming for me - I also thought it was too unstable :(
