I maintain Planimeter's Grid Engine https://www.planimeter.org/grid-sdk/ https://www.planimeter.org/grid-sdk/, which I also advertise as a 2D game engine. It also exists in the Lua ecosystem. I'm sad to see Corona Labs shutting down. I'm happy it's engine will be open sourced. There is some really great 2D game software in the Lua ecosystem, but hardly any of these products are actual engines. Defold and LÖVE aren't game engines, they're frameworks giving you load, update, and draw callbacks and some bindings to underlying libraries. None of these solutions will load levels for you, or provide entities or actors. Polycode is more of an engine than the former two, or even Corona. I'm sad to see another piece of software slated for end of maintenance in this space, but I'm hoping that it will inspire the development of more actual game engines that do more than provide a collection of bindings. I've wanted a Lua game engine that loaded levels, provided entities, had multiplayer out of the box, and everything else you'd expect from a game engine and not just some Lua C API bindings to OpenGL, OpenAL, and Box2D. It turned out I had to build it myself.
