Is there a best guide?

1. Not use huge lib, like Nape/Box2D or use external JS version for it.
2. Not use a lot of getPixels/getPixel32/ getData, and all pixel operations on BitmapData that set/return buffers or pixels. Include floodFill, getColorBoundingRect, because it require stop render and grab pixels from GPU
3. Not use a long property chain's in scrips, because it degraded compiler.
4. Use blendmodes from list: normal, add, multiple ... Other not supported now.
5. Not use a lot of separated sprites, 100 unique sprites is drop perf. Use ImageBitmap.draw to manual caching because cacheAsBitmap not supported now.
