What's the point of arbitrarily making the player play levels out of order? You can't complete level 7 until you've played level 8, so why not just switch their numbers?
Also, the offices don't really scale well enough, I think. Having to cover half the map with offices if you want to actually idle(well, more like 2/5ths currently, but it's only going to get worse) feels a bit silly.
I'm seeing symbols on the map and I have NO IDEA what they're supposed to represent. So I think I can say without exaggeration that the tutorial is really bad.
