Agreed, looks great and a built-in typewriter effect is very cool indeed ^^
Only two things i would love to see:
Aliased Text for TTF's or Webfonts, so you can use pixel fonts directly without needing to do spritefonts (as in i.e. Game Maker)
New Line break for the typewriter plugin BEFORE the sentence has started to write out as to prevent the jaggy linebreak in the middle of a word.
(THAT would be a killer feature, that no other engine i've seen offers out of the box).
But as it stands, it's already pretty exciting!
