This was a really original way to incorporate the theme! When playing through the first few levels I thought it was a really cool idea, but it would be way too easy because all you do is just run at the player. However, you were able to design really interesting levels that were both challenging and fun, while remaining just as simple. I thought the music/scenery change halfway through was really cool, too. There was one purple level with no music, just thought I should let you know. Overall, great job with this game and I'd love to see it fleshed out more in the future.
