Thanks to GamingOnLinux for pointing out that this crossplattform *no-programming* 2D game development suite has gone fully FOSS.
It can export games to HTML5 and native code (x86 Linux and Windows).
Read the original announcement here. The github repository is here.
Here is a small video to get you started:
- The IDE (in the IDE folder) is licensed with GPL v3.
- The Core library, the native and HTML5 platforms (respectively Core, GDCpp and GDJS folders) are LGPL v3.
- Extensions (in the Extensions folder) are using zlib/libpng license.
- The name, Game Develop, and its logo are the exclusive property of Florian Rival.
& you can find some example games here.
By the way: I also recommend to have another look at the Godot engine which has had many improvements since it became open-source a few months ago.
