The game Phoenix Spirit is coming to Android soon. To quote directly from the horse's mouth:
The game can be summarized as being an action exploration game in the same manner as Metroid, Castevania or Aquaria. The true goal in the game is to uncover the cause of the disease which is plaguing the mother tree.
To progress through the forest you will need to collect new abilities, cure diseases that stands in your way as well as collect hidden powerups. The Gameplay is comparable to a traditional shooter but with the freedom of flying. Using your accelerometer or thumb to guide Spirit through the forest adds exciting new gameplay in a whole new dimension.
and here's the trailer with, unlike some trailers, actual game footage...
