Skip doesn't work that I know of. I tried but nothing. Honestly, don't worry about the time limit. It doesn't really hinder you. I have a warehouse that has all full shelves. You will really only get maybe 3 orders a day that you can fully complete but, I send out orders that I can't full fill completely to get extra money. The lower rating doesn't effect you rating that much. Once you get further in game you will encounter more house with longer time frames and once you get the biggest truck you will be able to take damn near everything in the time frame. I can suggest not buying any other vehicles and just saving the 15K for the biggest truck since that truck makes everything so much easier and buying others to upgrade will just be a waste of time and money really.

Also, currently there is no way to remove the restriction or change any of the settings from the 2 options they give you to better suit your play style. I did put it in the suggestions and seen someone make a thread about it. All they said it that they would maybe think about making it so you could change them independently after the tutorial, but was not certain they would. They also mentioned maybe if there was a big enough interest they may look into it. So, maybe post in the suggestions and they may do it if there are enough people asking for it.

Thanks for the reply. It's a shame they didn't implement a tutorial skipping mechanism. Maybe I'll wait until they do. I didn't like it the first time, so I don't want to repeat it.
Unfortunately, only after playing for a while did I realize that the time limit prevents me from relaxing and indulging in meditative destruction. Even if there's no penalty, I still automatically remember it and start rushing. I didn't select this option because many games give me plenty of time to get everything done. So I always try playing on the default configuration first before removing the restrictions.
