You might think it's bad for offering it for free, thinking you may lose money, but if I can, I always download the game for free and decide what to pay after I play the game. Another dev did that, and was selling the game for $5, but I loved it so much, I "finally" bought it and paid $20! If I think it was "meh", you will get what you asked for, so unless the game is really bad, you will get money from many, like me, I am sure.
And the twist in the story - I love twists in stories!
