Well I have been plaing TPT since it's first release back in ummmm well years ago. followed all updates and then it went down for a few months so i was like omfg but I kept playing and then the servers came back on for about a month.
Any ways then i had to find out why it went down so i subscribed to this thread:
I've still got the old version archived just in case... looking back it is so basic and primitive, I'm all for Simon's (and others) new developments of the powder toy.
