Had a lot of fun with this one, 2 things I wanted to point out was the Cosmic Vending machine providing $300 less then the Quantum Vending machine that gets unlocked before it, was thinking the values might have been swapped. Second is the 'Levels' achievements, I'm not sure what those are about since I've made it to Prestige Lv.12 and have purchased 100+ of a single vending machine without any of the numbers changing from 0.
As for a suggestion! The timer for the Free Recipe for the Drink Lab is takes quite a while if you're not doing well with guessing, I was able to brute force the C and most of the B tier, but still spent about 3 extra hours waiting on the rest. So I was thinking a way to speed up the Free Recipe timer would be nice, maybe for every unlocked recipe you have can decrease the timer by 30sec each, that way you can kind of easily knock it down to around 15min wait for some of the harder to guess A and S tiers.
