Today I added a two-player-coop mode. I used usocket for portable TCP
sockets, and cl-store for serializing messages sent over the wire. The
protocol is based on sending keyboard events between the client and server
and running the entire game simulation on both the client and server. So far
I've tested it on my wireless LAN between a Windows and a Mac machine and it
seems to work reasonably well. I haven't tried playing across the internet
but I suspect my current scheme would require tweaking to avoid lag.
Here's the daily video:

Tomorrow's probably going to be mainly gameplay tweaks and bug fixes. I'm
also hoping to incorporate better graphics :-)
