I'm playing tutorial mode but after I get teleported to Egypt, I lose the ability to plant the Peashooters. I don't want to buy any power-ups or special items to beat these levels.
I've reinstalled the game twice already but I still can't plant the Peashooters. I used the Walnuts and Potato Mines to beat Day 1 but it was very hard and I don't want to play the whole game that way.
What am I missing?
