Ahi HTML5 game engine
About
Ahi is a work-in-progress HTML5 canvas game engine. It features an Entity component system (ECS) which is somewhat influenced by the ECS found in Unity.
Fair warning: Many features do not exist or are completely broken. :)
Using Ahi
I find that example code is the best way to learn, so your first stop should be the Ahi Examples repository.
More to come shortly.
