I posted asking about any non-Flash frameworks since I'm familiar with Flash and FlashDevelop. I'm considering learning something at the last minute.

I'm making a new post both to take any additional suggestions people have, AND to share the ideas that people added on my last post (https://ldjam.com/events/ludum-dare/43/$127775/any-ideas-for-simple-web-game-frameworks).

• Phaser (Flash-like, has good examples)

• Haxe (works with FlashDevelop, has frameworks like heaps.io, kha, haxeflixel with openfl -- but kha is low-level and may take a long time to get started)

• PIXI.js (www.pixijs.com), javascript webGL framework based on actionscript 3 libraries.

Any others are welcome, and I hope this helps someone!
