Fun stuff! My reflexes clearly need some work because the highest I got to was 75 in hard mode. It gets incredibly intense when the gems appeared at the edges and that brought on a dynamic experience.
The graphics are lovely but I do think there was an opportunity to have the spider be animated as it crawled around, and perhaps a cobweb in the background to explain how the little guy was moving. The overall sounds were harmonious and tied up the game very nicely.
