Javascript Engine for a simple 2D game.

I need to write a simple JS game. Basically, rewrite the "Open Doors" flash game in HTML/JS/whatever.

! The game is fine as long as it runs in Chrome for example. One browser is enough. So I don't have to use old techniques. !

So far I found Impact and Crafty. Impact is dropped as it's not free. Crafty looks a bit messy (documentation).

Which engine you guys prefer?
Which one should I use for this?

(Main points of the game:
- Arrow keys movement
- You control a single entity/object
- There is an animation when you move (not much)
- There are doors that need to detect how you approach them


What I meant by "messy" (Crafty) is this:
http://craftyjs.com/tutorial/entities-components/a-game

Half of the tutorials or documentation is missing.

Look at Pulse, Crafty and whatnot. They all look "cool". But how do I know which one is the better?

Sure, Impact is non-free, but is it Abelson non-free?

You are in the wrong board. Go back to /g/ or maybe boards.420chan.org/prog/. You won't find what you are looking for here.

just shell out the 100 dollars for impact. its by far the most complete toolkit out there.

Back to Hacker Jews, please.
