The Protector series of games have definitely jumped the shark. The first two are among the best Tower Defense games ever made. But then the designers kind of went crazy with adding features, and now it is just a mess of RPG-like upgrades and micromanagement that is simply tedious and repetitive.

Awful platformer. Worst dialog I have ever suffered through in a flash game. Hate the boss fight. After losing, you have to hammer through a long, tedious sequence before you can try again.
If a developer sat down and said, "I am going to come up with the most unoriginal, repetitive and boring flash game ever made," he would probably create Dragon Age: Journeys
