Hi there, I'm not quite sure what you mean but if you're looking for a review of the game you can check out the rating on itch.io which is under the "More Information" tab in the game description. You can also watch a Let's Play from Many a True Nerd here which is quite comprehensive (although the game is quite different now since this was 7 months ago)
Also please note that this is not a demo but a First Access game, which is similar to Early Access on Steam. If you purchase the game on here you will receive continuous updates until the product is final but it is a full game and not a demo :)
Hope that answers your question and Merry Christmas!
