In terms of ads, they're quite frequent, but I understand they keep the game free. I've had a few minor bugs, like getting stuck on the loading screen, which required me to restart the app. The updates generally improve gameplay, but occasionally, they introduce new issues instead of fixing old ones. The data usage is reasonable, so I can play without worrying about my mobile plan. I love the community aspect of this game; people are friendly and competitive, creating an enjoyable environment.
