Unique!! I don't think I've ever seen a game about hula-hooping before... but this fits the theme perfectly. What is more 'loop' than quite literally a 'hula hoop.'?
The gameplay was interesting and quirky, but the mechanics/controls didn't make much sense to me. There didn't seem to be much strategy in the way you increased your score, rather than mashing the A & D keys. Also, I see that someone else already mentioned, but it would be cool if you could spend the money on upgrades or items. Consider that as a next step for the game!
I liked the art and quirky music, and the whole premise of the game is really funny and creative. Congratulations on your submission!
