I do like the visuals and the idea. But it's lacking some music and it's repetetive. After a score of 1000 I quit since there's no difficutly at all. What I actually didn't like is the fact that the spider is colliding with the platforms. It's a bit buggy and the spider is almost always dragged down by it.
I think an increasing speed, no collision with the platform and platforms which you shouldn't click on or which gives you an disadvantage would be great. Just as an idea.
