Check out Battlemachy, a flash based shooter. You’re a dude mounted on a Pegasus armed with a spear. The game is mission based and in each mission you can only move on a clearly defined track. Some missions play out similar to space invaders, others are like star castle, and so on. You earn money based on your performance in each mission, which you can spend between missions to upgrade your gear with things like faster flying and shooting speeds. Simple fun with good graphics and a worthy friday fun link.
