This is quite impressive, and includes a nice behind the scenes writeup, too!

I remember wanting to check the original version of this a few times, but was bummered by having to set it up in a way that was comfortable running from WINE and only played it a few times.

Now that it got a port I may indulge a bit. Runs pretty well in my Firefox, and allows configuring the controls and everything (I prefer WASD). Pretty excellent stuff.
