Too many studios are too quick to throw the games out, but with these guys, I think they did so out of excitement, fan excitement, and maybe to raise some funds to finish it off.
I hate when studios get in the way and push them out regardless of what the devs say because it ruins the whole experience and can ruin games.
There is a surprising amount of polish to what's there, but there is much of the game missing and waiting to be released. It's worth waiting for it though. I got it free with Gamepass, so don't mind that it's relatively undercooked.
