Hey there, thanks for the feedback! There was previously a free build available, but that is no longer the case as the game has progressed much and the old build was no longer representative of the game. I've just updated the game description to avoid future confusion about that (thanks for the heads up). I may yet make another demo version of the game, but if so it won't likely be until version 1.0 or later, as the game is still undergoing changes. One option might be to purchase the Steam version and return it if it's not what you're looking for, though be sure to follow Steam's refund guidelines if you take that route. (itch's return process looks to be a little more involved: https://itch.io/docs/legal/terms#refunds ).
Cheerio!
