@2003and The easiest way to earn crystals is to put on a good show. Also be sure to alternate between locations, otherwise you'll gain less and less per show!
Gedanken gave me an idea: Add an upgrade that allows you to get more reactors, like when you buy the upgrade, you get a second tab where you can build another reactor! Like if you agree.
Before I played: Time to get the badge in the game!
While I was playing: HOW LONG IS THIS FRIGGIN' GAME?!?!?!
When I beat the game: Finally! It's over! Never playing this again :/
(this comment is for the creator) Will you do me a favor? Make a new AtmosFeast, but with no time limit. Ok? (i'm putting this in my favorites and rating it 5 in return)
