Really great work on all the visuals. I was really impressed with the liquid-like effect you got from the wobble shader on the title screen. I checked out the project to see that working under-the-hood, so thanks for sharing the source code. I only made it to level 2, but it seems intentionally made for a different gamer/audience. Mechanically though, I liked the idea. I might come back to it when I'm feeling more rhythmic.
Great style and I love the rainbow-colors!
