The slides from our presentation on "Unity and WebGL" are now available here: http://bit.ly/1G8Ju5f
We talked about the process of getting our game "Wonderball Heroes" to WebGL, and all the challenges, optimizations and other bugs we faced along the way.
It's pretty technical, but may be really helpful for all of you planning to support this platform with Unity 5.
Check it out, and feel free to comment / contact me in case you have any questions !
