In this game you control a helicopter, trying to survive multiple opponents in the form of enemy helicopters coming against you and anti-aircraft launchers on the ground, both firing deadly missiles at you. Once in a while, bonus crates drop from above but other than that, you're on your own.

The animated sprites are all done with CSS sprite techniques and all in all it's a nice little game, although some of the sprites could use some more work and the game as a whole could use a bit of optimizing.

Unfortunately there's not much information available on the site, so any technical details will have to be found in the source code. The page does mention that he's using ExCanvas to make it work on IE, but that's about it.

The demo itself is pretty simple, you just walk around a pseudo-3D maze. There's a bit of gun-wobbling and some jumping thrown in as well. In the default mode, the walls are rendered as single colored surfaces but there's also a textured mode which, even if it's much slower, shows that there's potential for Wolfensteinish action.
