Not Classic Macs, but Mac Classics: the Classic was an integrated 
Macintosh (like the iMac) with a 9" screen and a native resolution of 
512x384. A friend of mine has one, and we played Oxyd on it (together 
with a IIcx). http://images.google.de/images?q=macintosh+classic
Funky games for the classic also included Snoopy; 
http://snoopy2.sourceforge.net/ . Enough of the shameless plugs.

I just sent the new OS X version to MetalSnake for testing; the last 
one had a stupid bug, because I hadn't defined MACOSX while compiling. 
To remove the bright seams, I hardcoded the colour depth to 32 bit, 
which messed up the colour keys for images which are loaded from 24-bit 
pngs. So I converted them all to 8-bit. They seem to be 8-bit in the 
newest CVS, anyway.

On the topic of porting to Classic Mac OS:
a) I don't have CodeWarrior. Said friend has CodeWarrior, but it's 
version 0.003, i.e. old. I guess that porting Enigma with that would be 
even more of a pain than with MPW.
b) MPW. Don't get me started. I have heard that people paid lots'n lots 
of money for this. I don't believe it. On the other hand, Linux is a 
free UNIX clone, which people paid lots'n lots of money for, so...
It's basically a command line replacement for Macintosh, which would be 
a good thing, if only it was a standard posix-like command line.
I guess that it would be possible to port Enigma, but you'd have to
1) rename all files. MPW doesn't understand .cc. It doesn't understand 
the concept of file-types-by-extension either, so you have to set type 
and creator (old Mac file type metadata), but it understands enough to 
die if your sources are called .cc. Grrrr.
2) compile lua, SDL, SDL_image, SDL_mixer in MPW. This can be done, and 
I believe I have done it, but it wasn't easy.
3) compile STL. This is where I'm hanging.
4) compile&port Enigma. Unknown problems en masse.

Compiling STL under MPW doesn't seem a job for the weak of heart, or 
not-utterly-extremely-severely bored. Feel free to try it, but I guess 
that this would be a major undertaking, after which you'll have learned 
a whole lot of useless stuff about a dead OS.

Okay, till then,
Johannes
