Sadly this game really is early access - so early acces, that it's not in a usable state yet.
This starts at the tutorial: The tutorial ends after explaining the interface - and then leaves you alone to find out what you are supposed to do. Out of all buildings available in the game only two or three are actually usable yet, all others only have a "graphical userinterface not yet implemented"-screen.
The graphics are okay, just be aware that you'll never get to see something that isn't shown on the screenshots already: When you click the "End Turn" button in the upper right corner a night-day-cycle animation is played, and you'll see this animation quite often.
About the game itself: I have no idea. It sounds promising, but the lack of tutorial definitely keeps you from actually playing (unless you like to figure out which technologies in a tech-tree you need to explore to get an actual result).
Absolutely nothing in the menus has a comment on what it influences, some menus aren't even translated yet, and the few things that already work don't really do anything - e.g. Prestige-points: You can hold press-conferences, which increase or decrease your prestige in four different fields, depending on your answers to the reporters questions.
But that's it - four numbers go up or down, and you have absolutely no idea what the point is. I guess it has something to do with your contracts and how much you earn from them, but for like everything else I'm left guessing.
At the end of the day it's simply far too early for this game to exist on steam: Most other Early Access-Games are playable with not all content yet implemented, and a lot of bugs - this game doesn't seem to have lots of bugs, simply because nothing exists that could be bugged yet.
Conclusion: I'm looking forward to the game, since the idea really looks promising, but I can't recommend buying this game YET. My recommendation: check again in two or three months, because at the moment you'll be heavily disappointed by spending 18,99€ (or the equivalent amount in your countries currency) on this game.
I'll keep an eye on the game and check out if the updates improve it and will update my review.
