I must admit at first I was pretty lost and it took me some time to realise that I had to repeat to click on my dude to get him going again. At the same time though, that 'feature' is what eventually lead me to discover that the other stars echo back. Not sure if making the players having to click on their dude to move was a way to teach them about the echo, but that is how learned it, and was a great 'aha!' moment :)
Anyway, what an awesome mechanic! Lighting was well done and overall a nice relaxing game.
