Hi teamlazer! I would say yes, this is a good idea. We're currently doing the same thing with our early access game, Mondrian - Plastic Reality. The reason we chose itch is specifically because it is much more welcoming toward early, experimental, and incomplete titles than Steam (even though yes, we also have one up there that we're still working on and will be updating at some point). itch also isn't the kind of place where you can expect to host "get rich quick" asset flips and find success, ala Digital Homicide. If you're nervous about reviews, you can set the game to Free or Suggested Donation instead of making it a truly premium project, and use the Discussion Board feature for tracking feedback and bug reports instead of trying to sort through a big list of comments at the bottom of the page.
Hope this helps!
