I put ~20 hours in and purchased the final building so that you don't have to. Nearly identical to the first game with better visual polish. Very shallow mechanics that are a good enough time waster if you like watching numbers go up. Many ideas feel half thought out and not balanced in the slightest. The last challenge is incredibly insulting and I would have given a higher rating if it wasn't for the laziest ending I've ever seen in a game. Its disrespectful to the player and to your own game.
