Some of you might remember when a 3mb flash animation could pack in some 5 minutes of animation, with the more advanced ones even having chapter/scene selectors, which could also include clickable easter eggs and other kinds of interactions during the scenes.
You clearly miss the point, intentionally or not intentionally, I don’t know. I thought it’s clear what the point is.
On one hand you have a tool like flash an integrated tool similar to other design tools, timeline, coding interface (that works with the timeline and elements on the board, thousand of libraries intended for people using flash, vast community resources. On the other hand you have pure coding. Not sure what your issue is. I don’t have time to go the full circle with you. That css game was made by a 10x programer. The same game would be made by a designer in flash.
