Ok at first but gets very boring quickly.
It seems as if the counter doesnt go up to 3 digits and a task is broken (spec. the water tower level 3 task) in game as well. Thankfully there are no achievements that are task-related. I had some old items as I didnt feel like selling 3 items just to get to them as the game requires you to click in very specific spots to get cash/exp or to sell structures. The game itself is kind of a bore once you are able to unlock the Squid structure. After that the whole game is more or less click, click, click until you get 9 planets and to level 100. Some suggestions might be a button that would auto-loot all available structures and maybe some difficulty to keep it entertaining. Perhaps add ever-increasing amounts of money to be spent after so many minutes for upkeep/salaries, etc. as you expand when you buy a new planet.
