The gameplay was super easy, not difficult. Then occasionally a random hard puzzle. The only problem with that is you have to get through the manegment sim part of the game to access puzzles. You know like before the next level upgrade your base, first upgrade the farm, to do that wait 3 hrs or pay moneyI saw this game in adds countless times and I thought OK it looks like a cool puzzle game. Had a few times it froze, the sound occasionally is static, it takes a while to load. Just disappointed
