I have also been writing a demo/game for the PC-Engine, using the fantastic
HuC compiler. And now, I have finally created a home page for it.
It's called "Flipit", and it is basically a version of Othello for the
PC-Engine.
Please take a look at:

It can also be found on the "Utopia" site with other PC-Engine demos.

And it will be included with future releases of the HuC compiler.
