Enjoying the game so far. Got curious and wrote a little ruby script to do some checks on the data files.
I found a few questionable things in rooms.txt (that probably don't break anything), 2 instances where the command end is incorrect in interactions.txt (which causes the command after the bad end text to be ignored if I remember enough qbasic to understand the code), 36 duplicate commands in interactions.txt, and 24 (or 22, keep reading) extra commands in interactions.txt that won't be read (i.e. file says 1553, but I found 1577 or 1575 if you don't count the 2 with bad command end text). Duplicate commands are those where the commandString, requiredRoom, and requiredItem match.
Should I post the list of things I found here or post them somewhere else?
