A lot of fun!

hope to see a 5! frustrating at times but have to be very strategic, also some more options like hotels, bowling alley, go karting for businesses would look cool.

Trial is a joke

I was not impressed with how short this trial version is. It just abruptly stops in the middle of a campaign only about 2 mins into the game. At least let people finish a level before making them decide to buy. Makes me not want to spend the $2.99 for the full version.

Build a lot 4

I love this game! Must be strategic on many levels and some are very frustrating! Can't wait to progress.
