You deserve credit for making something creative. It's too bad it was so frustrating. It's particularly annoying when the bits themselves are so hard to get. I was hoping more for being able to collect them after you died. I do have to give you some more credit for having some good music. It's funny to see the character's eyes turn into hearts.
I don't know what these little suns are doing everywhere. All I know is that they are unkillable. It gets to a point where you have to double jump for everything to get around. I'm glad not using that isn't a medal. The setup is very nice too.
