Realy amazing game system. But too short.
Take it to the advantage and make full game with that system. It will take the world! :)
As you said, the flash have problem - the game is too big and testing things is realy slow. Split the game to more part. Next piece - awakening 2 - etc.
Saved game can be exported and uploaded to the next part of game :) (And you may do the next part based only on saved game from part before.)
