A simple entity system written in Haxe, based on the Artemis ES: http://gamadu.com/artemis/
haxelib git hxE https://github.com/PDeveloper/hxE.git
The number of components you can use is limited, since each component requires a unique bit flag. The default is 32, since the default BitSet is the SingleBitSet. You can define compiler flags: -D hxEDoubleBit which will increase the limit to 64 components, or -D hxELargeBit which allows unlimited components, but is also slower (relatively by a lot, but not sure if noticeable).
I'll be adding to the Wiki in a few days. For now, see the samples included!
