When comparing Genome2D vs Polycode, the Slant community recommends Polycode for most people. In the question“What are the best 2D game engines?” Polycode is ranked 32nd while Genome2D is ranked 47th. The most important reason people chose Polycode is:
Polycode uses Lua and C++ to create native applications for Windows, Mac, and Linux. Mobile platforms are planned for the future.

Ranked in these QuestionsQuestion Ranking
Pros
Pro Lightning fast
It's the fastest gpu-based framework out there for flash. It's beautifully optimised. It has very low rendering latency, low level OpenGL calls that other tech simply cannot do (ie Unity) due to Stage3D, and thus can render a lot more data quicker
Pro Cross-platform mobile, desktop and web
Supports Windows, Mac OS X, Linux, iOS, Android, Web and native Flash.
And with the HTML5 export, it also potentially supports development for the Wii U :)
Pro Haxe!
Haxe is a strictly typed programming language that saves development time but still compiles high performance executables, and can build for tons of different platforms (flash, c++, html5, java, c#, etc.)
Pro Access to direct draw features
Has access to direct draw features so you can make you own rendering structures (scene graphs etc).
Pro Automatic dynamic batching
Automatically batch geometries with dynamic batching techniques (by using constant buffers).
Pro Component based architecture
Pro Can create portable native applications
Polycode uses Lua and C++ to create native applications for Windows, Mac, and Linux. Mobile platforms are planned for the future.
Pro Free and open source
Polycode is free and open source (released under the MIT license). The source code is freely available on GitHub.
Pro IDE for 3D editing
Recently, the editor and its integrated tools have been released in compiled form. Features coding and scene editing in one application.
Pro C++/Lua
Polycode is distributed in a C++ form as well as with IDE. And there's an additional LUA-based scripting system.
Cons
Con Lacks documentation
The API documentation is minimal, there's not many tutorials and the ones that are there are very small and only cover the basics. If you want to learn how to properly use it, you have to ask the community or read the source code and figure it out.
Con Not too many games to showcase it
Con Slow development rate
Con Abandoned
The project does not seem to be maintained anymore: there has been no new release nor commit since mid-2015.
Con No mobile support
Doesn't have support for Android or iOS.
