This game is a perfect representation of Capitalism. No matter how far you update, no matter how many upgrades there are, no matter how you expand your resources extraction, they are finite, and while they have an end, the hunger of the Angel Investors only increase, and once you get to the limit, less and less Angel Investors will want to come with you, until, after an unilimited amount of time, no new angel will ever appear (if waiting continuously). Your system will be on a dead progression, with an unlimited amount of zombie investors that never leave you (Apple?), and shall not be replaced because nobody else thinks that that resource consumption is worth it. Happy for you, that won't happen before you die, which makes it even more capitalistic!
These graphics... They smell like those games that get to Hot New Games section for mass control of accounts by developer for one day, even though it is extremely bad.
I've already got this done. It will be included in the big patch later tonight.
