Wow elliott! I got a chance to watch the video, but haven't played yet.
Thanks so much for participating in the contest!!!

Today is New Years Day 2010, the deadline for the FLGC 09 contest! For those
of you who haven't posted your entries, go ahead now (completed or not)!
There's no judging phase, the point is for us to play each other's games,
provide feedback, and of course learn about lisp games. On top of that, I'm
hoping people will use their 7day versions as the basis for something bigger
in the future.... forcing yourself to make something complete in 7 days is a
great way to start!

Ok, here's my suggestion on what do to next. Everyone post the URLs and
instructions to their entries if they haven't yet, and then I'll make a
small webpage with all the entries. please send a screenshot if you can, so
that the page will look nice.
Then we can play the entries and comment on the mailing list. I'll work on
the page today.

New Thopter page on the Blackthorn wiki which you can put on the FLGC page:

http://code.google.com/p/blackthorn-engine/wiki/Thopter

And here's a screenshot for you:

I just played Thropter. Great game. I think it would be a good idea if  
you could change the direction you're firing/looking?

Congrats.

Thanks for the feedback!

Have you tried missiles? (Left Ctrl or Alt) They seek to enemies and can
thus fly backwards.

Perhaps another thing which would help would be to introduce formations for
enemies which don't involve flying to the bottom of the screen, so they
would always be in front of the player.

One thing that frustrates me about the AI is how it has a tendency to fly
off screen when dodging bullets. I'd like to figure out a way to keep the
enemies on screen at all times, but I'm somewhat at a loss for how to do
this without allowing enemies to get stuck in the corners of the screen.

I haven't played your game so this could be nonsense but you could make 
the screen wrap around.  So an enemy going off the screen on the right 
would reappear on the left side.

I wasn't really planning on playing the game on a torus, although I suppose
that could work. But most scrolling shooters I've seen play on a
non-wrapping field.

I was thinking more of adding a more advanced AI (i.e. one that actually
tries to attack you instead of just dodging bullets). I'm not really sure
what the right direction is, but I think I might try playing around with
Markov decision processes.

Thanks for the input.
