: Theoretically it may be possible to play an entire game this way as long

I'll have to try this... Looking at player.cpp line 207 in the Aleph source, we see that the only damage type allowed to bypass invincibility is fusion while the suffocation code (line 1103) attempts to perform suffocation damage. Are you talking about the original game engine or Aleph One? Invincibility handling was changed when MML was added to the game, perhaps suffocation could kill you while invincible in the original games (the earliest version in the CVS archive still has Loren's changelog entry regarding invincibility, and I can't find the original M2 source archive).
