you need to make an unlimited stage, so that way we can still get levels and gold after we have defeated EVERYTHING and have nothing to do. Also, achievements like fully upgraded one unit- 10% more gold per enemy, or slight increase of attack damage. I think that If you added these to your game it would increase the overall like of the game.

its funny, mummies actually will give you money that demons, and wizards more than demons too... even by click because mummies take 3 clicks, when demons take 6, so when they are doing roughly the same per fill, mummies are still doing more.
you should have the end price of all the fish like if you have 5 whales and they are 90 each it would be 450. or you have to buy a money checker or something
