Oh! My bad for not keeping up with the Steam version! Is there a way for us testers to download it or do I get to purchase it again? I haven't been able to find info on this. Best of luck in the final time of polishhhhh!

Go to your itch library (https://itch.io/my-purchases) and click on "Download" under TumbleSeed and that page has your Steam key.
i believe you can request/redeem your steam code on the download page. If you search your email for "New TumbleSeed build! Now in beta" there should be a download link in there that takes you to that page. It's a bit weird since I think it needs to be a unique URL so I can't directly link it here it
