I have been waiting over 40 minutes and have only gotten two customer in Chapter 1. The clock still showed more than half the time left. Is this normal? I have uninstalled and re-installed this game and it has not helped. Any suggestions?

Is so difficult to click ,let my finger so hurt :(

Ok, I have been seriously trying to earn 12 hearts on the mini game challenge that involves safety controls, but this is honestly just way too hard. The mouse controls feel slow and sluggish and the best I can do is earn 8 hearts. (I think there are a total of 4 customers that request this challenge.) There isn't a way to lower the difficulty level in this game, so is it possible to please improve this level? It's honestly frustrating me a lot. Also, another complaint about this mini challenge is that...

when will this game come?

After all levels are complete, game ends or can one continue????
