It's a good game and very fun. The problem is I've been grinding and watching ads for a while to build my truck without spending any money. But level 6-5 is the last level you will get to without spending money. Very sad. Put a lot of time into this game for it to turn into a money grab. Don't download unless you wanna spend loads of money because you can't finish without it. Don't care what the dev's say. And nobody wants to join groups for rewards or watch ads for a month to pass 1 level. SAD!
