Lots of bugs in the tutorial, after I didn't manage to put stuff on the green tiles for the first time, the game didn't allow me to do it at all. I just dragged the tower with the cursor and couldn't place it anywhere or get rid of it anyhow
Pretty weird: since day 45 the approval started to decrease even though I got 3-5 start from costumers. At day 56 it was 16 and I had like 3 costumers a day. Don't think it should work this way.
