The cheat is working,you just can't understand how.Go to a shop you gotta have enough money to buy that thing(BUT DON"T BUY IT)click on it,then click that button where you go to sell your things.then click sell and that's it,you get money,if you do that three times on the same thing,it's name will be null,null.....like 50 of them.It works on spells too;-)
3+ is way high limit for a game that was just started,or at least looks like that,this can be a great game.2.45 is a great rating for a game in this state,i think you should work on this game...it can be great to have a classic TD,without mushrooms and stuff.
