Used to be grand, but then caught the fast money bug. Removed premium gifts while increasing costs. Some upgrades costing millions of eggs ($$hundreds in value). They introduced a buggy fuel mechanic with rounding errors not in your favor and needs multiple egg types but you can still only make one kind. It sucks eggs now. Oh yeah, forgot to mention their ads: they allow ads that force open the game store when you try to close them after completion. Very sad how far they've fallen for greed.
