Godot Engine

Godot is an advanced, feature-packed, multi-platform 2D and 3D game

engine. It provides a huge set of common tools, so you can just focus on

making your game without reinventing the wheel.

Godot is completely free and open source under the very permissive MIT

license. No strings attached, no royalties, nothing. Your game is yours,

down to the last line of engine code.
