This is a development allegro.js library. It contains documentation and human-readable code inside. If you don't know what to pick, pick this one!
This is a minified version of allegro.js. Use this only for releasing your game, or it will be really had to debug, and code completion won't work.
Go to GitHub to get everything in one package! The library, examples, docs and some useful info! You can help create allegro.js too!
