Would love to try this but, without a way to try it $30 is pretty steep.
I watched a couple of Youtubers run a demo. I've paid more for less and it looks like a fun challenge. Plus there's the probability that I can have my comments taken more seriously as an early user. Helping a game designer is much easier than complaining about those few things I don't like in a game. I'd rather pay a little more and get to add my opinion, than have to deal with the issues of coming later and dealing with the "but we added this because users wanted it" that I've seen in other games.
