You need to increase the amount of money you earn A LOT. After level 10 you have to play a level like 10 times to earn 1 decent upgrade. Better yet, give gold for matched units too.
Quote from the change log:
"Fixed the achievement Pop-up so it doesn’t cover the Donut buttons. It still covers the donut icon a bit – LET US KNOW IF YOU HATE THIS STILL!"
Of course I still hate it !!!
OK, with the latest update you jumped the shark in the fridge. It´s all been said before, if you want to improve the game further, roll back to 1 month ago, EVERYTHING was better.
LOL, played the game for the second time and got this message:
"We have detected that you are trying to hack the game.
Any future attempts to hack will result in a permanent ban and the loss of your base. "
