Love the honesty, but if it's not a complete game, and you are admitting the completion "won't be for some time", I think most people, like me, will wait.

You should offer it as a free OR a $3.99 download. Then people could see what the game was like, then when the finished game is released quite a few of us may pay well over the $3.99 price. Unfortunately, on Itch, if I pay $3.99, and it turns out to be the best AVN I have played, the is no itch system for me to pay extra.
