I got an e-mail from this site that apparently lists and reviews software a lot like the old download.com. They asked me to keep the info updated when we make new releases. They must have added it last August, and it has 825 hits since then. There is a direct link to Smiley Pro too.
Re: Softpedia
That's great news! I added the game to a few freeware indexes, but I was beginning to wonder if anyone would ever link to Invade Earth without prompting from one of us. It looks like people are finally starting to find the game on their own... I have noticed a lot of referrals from other sites recently.
