I am really enjoying how they mix-up each level for different challenges to workaround. My main concern for titles like this is that it becomes stale and boring. I thought I was going to put the game down after the industrial map until I hit Duckworth. The 3 levels on the map before, the snowy area, weren't that great. The exception was Milton because it teaches about training, which is incredibly important on levels going forward. I hated Milton at the time, to be honest. Once I got to Duckworth, it all kind of clicked together. I read a lot of folks struggled with it, but I felt it pretty easy and enjoyed the change of pace. The public tasks were often easy, and doubly easy to discard if they weren't easy. I was worried after Duckworth that game would go back to a boring level. I wound up choosing Sweaty Palms, which continues the change of pace by having constant natural disasters and a/c units. Both require more and better trained janitors than previous maps. I've two starred Sweaty Palms, working toward 3. I'm at 68 hours and I think I will continue through. I'm hoping I don't tire out before the end. Easily worth the asking $35, imo.
