Can you provide a bit more info about the programming language we have to use in this game engine and what the process of creating a game is  like?

Since Blazium is a fork of Godot it has all of the same features, like GDScript as the main scripting language and scene based design, but we have added extra features like discord api integration or SQLite database importing. We are also managed to pick a lot of Godot 4.4 features, like the embeded game window, without breaking compatibility with Godot 4.3 projects.

You can find more information on the features page and in our blog.
