This is a wonderfully fun game. However, developer needs to let the buyer know that there is a finite number of weed strains for this game (I believe its around 250, give or take). I purchase 190 "reveal a letters" for $9.99. Before I had the chance to use them, the number of weed strains was exhausted, and when the game then started over, all of my "reveal a letters" I had purchased were removed. I lost $10.00. I was NOT happy about this. Just let us know thats what will happen so we dont waste our money, please! Its dishonest. Thank you, Apple, for addressing this and refunding my money! Developer, please run an honest app and fix this!
