Anyone playing this game for the first time: DO NOT BUY THE ORE TRAIL REINCARNATION UPGRADE
Unless there's been an update since this comment that has addressed the problem. As it stands now during late game I'm crashing on 80% of runs or more, almost always caused by an error attributed to ore trails. And since you can't un-purchase these upgrades (AFAIK), it essentially corrupts your save file.
Great game otherwise though. At first I thought it was a little ridiculous that burger customers who ordered a "bacon-chicken" burger wouldn't accept a "chicken-bacon" burger. But then I realized that's precisely why I can charge $800 for a piece of bacon on a plain bun and wait an entire day to even start making it. My customers are willing to pay a premium for utter perfection in the end product.
Then I made someone a burger with 6 pieces of both burnt and raw meat atop their requested ingredients all garnished with a skyscraper of condiments alternating ketchup-mustard-bbq-mustard, closely resembling the red-yellow-black-yellow banding pattern of the highly venomous eastern coral snake. A "burger" so vile as to be imperceptible by the reasoning parts of the brain, forcing out a limbic scream of "DO NOT EAT" that echoes viscerally through the sympathetic nervous system.
Yet not only did the customer accept this nasty patty, they paid in full and left without complaint. This made me rethink the nature of my business entirely. Had I become too big to fail? Was I so popular a brand that not consuming my burgers was unthinkable? Or was I even selling food at all anymore? Maybe my sandwiches were so sublime, so picture-perfect each and every time that they sold themselves on aesthetic quality alone. Maybe we're not a restaurant anymore, but something akin to a fine art gallery patronized by wealthy benefactors looking to discover the next Burgnini or Salvador Deli.
With this revelation, I understand now that I have the power to control trends in the upper echelon of the art world with the flip of a patty. Who knows what sort of surreal sandwiches are being prepared right now as a result of my execrable experiment? If only I could witness them and perhaps be given the opportunity to pulverize them where they stand with biting counter-burgers, or nurture them and foster a collaborative environment of forward-thinking burger-based artistry to propel humanity to new heights. The future is fried.
TL;DR: Suggestion -- let us see and influence the work of our fry cook contemporaries.
