Had almost give up hope on this one. Need to fire this baby up as soon as possible. (Would be neat if someone came up with nice colored lighting for these maps at some point, but no need to hurry.)

Congrats for finally getting this huge project out of the door, a considerable achievement! 

Apparently, there's a bug in the map e3m3: Once I found the gold key (with it's cubical grid lowered), I'm unable to catch it. Is there something else to be done to take that key? I feel it's a bug. 

Doh!
