Great, I really enjoy the story turns and art, kind of Another World vibe!
I lost in the arena stage where there are birds and then beasts, and the second time I entered there were birds, but no beasts, so the game broke. :( Only had 9 gems.
Also, at each bow shoot the game froze for me for a second, but only on the arena level and only when there are baddies coming.
Oh, and I used Firefox, didn't read the description before playing... :/
