I also implemented the ability for the crystal to actually be defeated, but it doesn't yet trigger the end of the game - it should, in about two hours.
Level transitions are working fine. Now all I need is some content to actually put in the levels.
The icon in the upper right of the screen is the energy gauge for the player's attacking move, but alas, it doesn't yet hurt anything.
I still need someone to do a voice over/song for me, if they have a microphone.
