make sure that you buy the things that will make you the most money...like upgrading your pie freezers to earn $15 more per pie...or your drink machine to earn $10 more per drink....
i also think it's important to have 3 ovens...this way you can start a new pie as soon as you take one out...i do this by picking up a raw pizza, then click twice on the oven to get a fresh baked pie, and at the same time, put the raw one in the oven...so when you have three ovens, you always have one of each flavor pizza ready.
I am stuck at level 47...i serve every customer without one walking out...but for some reason, i'm still not making enough money to reach the $ goal for that level....even if spend $10,000 to train the chef to make exclusive recipies, i still can't earn enough money....also at level 47, the opening round reads : "When we opened this morning, we found Rebecca's recipe lying open on a table...Did someone copy them? "
I can't beat this round for the life of me....i'd appreciate some help too. Good luck. this is a fun game...
