I finished both difficulties. I really really like it. Love the idea, it's really fun, the music is nice and chill, the alien audio is cool, the art is pretty. Feels like a fun single player board game! Wish there were more events, and that it was a little better balanced, so the events dictated gameplay decisions a little more. Also, for me, the random star "punishment" ended up being one of the best strategies to get around the map fast.
I see a lot of potential for a really fun full game! Hope you keep developing.
