Zebolus, Zombie exodus etc

Hi! I've never heard of either of the games you mentioned in your post here, but, after reading your description of what appears on the screen during these games, I wonder if they are text-based games. There are quite a few text-based games for IOS, those I know of being by a developer called Choice Of Games, where there is a story and you decide how the story continues by ticking one of at least two choices at the end of the page: once you've made your choice, you hit the Next button and the story continues, with more choices on almost every page. Is that perhaps the kind of game you have installed, seeing the title and not knowing how the game works? I realise we can't all like the same kind of games, and text games are boring for some people, but it's still better to choose a game after finding out more about it: even if a game title sounds exciting, you have to be sure that it's the kind of game you want to play, so it's best to read the description of any game before you install it. Of course, I may have totally misunderstood your description of what these games are like, but, as I told you before, both titles you mentioned are totally unknown to me, so, if I didn't explain things in the way you hoped I would, I apologise for that.
