Hi, we're really interested in using the itch refinery as a way to gather some early feedback for our game. At the moment we're considering adding just a single level for play-testing, and then increasing the content over time as the game progresses.
What we'd like to do is offer the in-progress game for free, but limit the number of people who can download it. I can see how to limit the downloads using a reward, but it doesn't seem possible to create a free reward. So, is there something I've missed, or is it not possible to do this at the moment?
