Finished up a game engine and a couple of browser games here:
http://joe.csoft.net
Features:
-rotated/scaled/lit sprites
-sound/music generator
-pixel-perfect collision detection
Some more info: My engine is probably best suited for arcade games that can take advantage of the collision detection. It runs at 125 fps internally so the collisions are real accurate regardless of the actual fps (game logic and rendering are separated).
