Great game! I used to love playing PvZ on my phone when I was forced to be somewhere I didn't wanna be as a kid! Like some other people here, I had an issue in the first few levels where some tiles at the bottom just didn't let me place a robot, but it seemed to sort out later, or perhaps I just stopped causing whatever caused the issue. I think the first few levels in general are a bit confusing, I was pretty lost on what I was doing, what each robot did, etc. And that is my fault bc I didn't wanna read everything in the almanac. But I'm actually glad I didn't, because I was pleasantly surprised as new enemies kept showing up as I progressed through the levels! And I think their designs were intuitive enough for me to figure out how to deal with them all on my own! I had a blast after about level 2, once things started picking up and I got into the flow of things, really fun game!!!
