I forgot this was a prototype game. Absolutely absorbed gameplay wise. A little lacking on the message logs, but it looks like the game is really balanced and is likely to get deeper as more development happens. They know which part requires a lot of waiting, and puts a minigame to speed up the process. The UI is basic, but it goes so well with the theme and doesn't shove everything at you all at once. It actually requires some thinking (not too much) at the beginning for some resource management too.

It's about an hour long, maybe a little less or more, but it's an hour that I won't take back. Again, I can't believe this is a prototype. It's more than most "beta" or "early access" games.
