The music was good but I'm not sure if it fits the game? I wish there were some sound effects for the bullets and the enemies, maybe just not enough time to finish? I was engaged enough to get a score of about 130 but it was a bit too easy so I stopped playing as there wasn't really much of a reward for going further. Not sure the rejuvenation theme fit with just allowing your character to heal from dead enemies. Still, the controls are good and I did like being able to heal from lots of dead enemies at once. It could be developed further where it would be part of your strategy to kill the enemies in one area of the screen so that you could quickly heal, but at the moment its too easy for that strategy to matter.
