I like what I see so far. When I first clicked to start, my worm faceplanted into a rock 1 tile below the top of the screen. It took me a while to figure out the game isn't frozen and I was just game over. The inputs aren't always registering and I notice some image flashing around his butt. I'm guessing some restructuring of the scripts would improve the performance.
The artwork is quite nice, and the warping music fits well with the atmosphere (and the dying flowers, haha).
