Far too expensive for so little. Can't make the character requirements bigger in events, so you can't see what's needed, similarly the possible character cards you can win need to be tappable so they are readable. Too much of a grind to be fun anymore. Doesn't respond well to taps in general. Needs work for sure, but it could get there. Very very difficult to get new characters, the number of cards needed is a bit high. If it weren't for the instawin feature I'd have given up by now.
