I found this a really fun and new concept. I don't think I've played a game much like this before, and I really like all the ideas involved, building a city somewhere super inhospitable and having to personally push away threats.
I do wish it had a bit more polish. With no sound, no warning of meteors, and quite a high difficulty, I got a couple of cities to the 30 second mark and then gave up. I think with a bit more escalation and feedback this could be a pretty fun game to play for a few minutes at a time.
