Wow this update is great! I managed to finish the game!
The challenge involved was just right to where I didn't want to quit.
Only feedback I have now is that I had no idea you could shuriken through the enemies until I read the comments of other people. I had thought that only the purple zones could be used with the shuriken. It would be nice if there was a note or hint when you first encounter a shuriken zone of each type.
