Hi everyone! So here's a quick guide, how you can improve your time, on City map. There are two parks in the City map, which are surrounded with smaller block houses. Find one of those, and on the way there, collect as many small pieces as you can. By the time you get to the park, you should be big enough to swallow all the things in there. After that, the parking cars in the area should be your next target, and when you're big enough, you can start swallowing the smaller apartment buildings that surrounded the park. With that technique, you can easily grow big, in much less time. I hope I could help you with this. Have fun, and good luck with reducing your time.
