VERY creative concept for an idle clicker, and the flavortext gave me a good chuckle. I feel as though it could have benefited from having the shop elements be in separate windows around the screen instead of tabs on the same interface, which would give a nice vibe of "running around". I also couldn't tell if changes were supposed to be happening in the viewport? It feels like there should have been a lot more artwork onscreen.
All in all, loved the idea of a clicker about seeking out aliens in deep space, though the silliness of the flavortext felt somewhat obligatory. Maybe if the story direction were a bit more somber, it would have become a really memorable piece about finding civilization out in the loneliness of space. Just a thought I wanted to float!
