Heres some news from the Senile Team:

Good news, PC gamers! The playable demo of Intrepid Izzy is now also available for Windows!

It is basically the same as the Dreamcast demo which was released earlier, except in HD resolution and with a few touch-ups here and there.

Download the demo from the Intrepid Izzy website.

We hope you will enjoy this demo, and are looking forward to any feedback that you might have.
