Great game! Only suggestion would be to remove the 20 ascension achievement or to add more achievements to expansions, meat units etc. As a completionist, I feel the need to get it, although I'm only on my 4th ascension and my swarm is so stupidly powerful that I can achieve the last meat unit in a matter of a few hours.
