Playability:
The makings of a great space politics simulator game. Really liked the different planetary interactions and different ways to "win". Just needs some time and polish.
Theme:
Fits the theme reasonably well as you're the envoy for your entire planet and all eyes are on you.
Cleverness:
Really liked the different interaction methods and responses for each of the cultures. With more time this could shape into something incredibly interesting.
Artistic Style:
Simple and consistent. Reminded me of older flash games when we used to create characters out of simple shapes. Good stuff.
