Too simple for my taste
Too simple (the background, music and sprites) and not enough thinking or reaction...etc. involved (I think a major thing that made it look simple was because I'm so zoomed in). Some skill needed...but only to make sure you move your mouse off screen and basically die. Instead of a dragging screen around feature, you should have it so by leaving your mouse at the, say, top-right corner, the guru continuously moves that way (until I let go of mouse). Level editor wouldn't be so bad either.
