It seems there were a few disconnects between my developer build and the public build I put out, all of which are hopefully fixed now that I've done a clean run through on a new build. From what I played, the messages should be fixed, and as for the burgers, the game should end once you fulfill all the orders after time has run out.
I plan to make more intuitive and better explained additions to the minigames in further updates, so I hope these sorts of things don't happen again. If you do try out the new build, please let me know if there are any issues that I should try and replicate and fix--really sorry that you guys have to temporarily play guinea pigs for me... :')
