Haxe is a garbage-collected language, and in general, it uses the GC of the target platform (the C++ target includes a runtime with a conservative collector). So you'll run into the typical issues with writing game code in a GC language - being careful about allocations and deep reference hierarchies, pooling/reusing objects, etc. Haxe doesn't really change anything here. Haxe does expose some platform-specific features that help though, such as C# structs and pointers/unsafe code, as well as platform-specific API's for interacting with the garbage collector (e.g. http://api.haxe.org/cpp/vm/Gc.html http://api.haxe.org/cpp/vm/Gc.html). You can take advantage of these while still writing cross-platform code with the usual tricks of conditional compilation.
