The game is immediately addictive at the beginning, because not everyone can offer such a quality game on a phone. You'll get stuck for a month or two, but if you play a little at a time. then you can do 4. And then the game starts to get boring, because there is almost no new gameplay, although events can add a little variety, they are time-consuming and too casual, and it’s better not to talk about the children’s short storyline at all.
The game turns more into:
1) you have money - spend as much as you can and maybe you will be lucky and get what you wanted.
2) no money - grind a lot and wait until you save up for something.
In conclusion:
1) the game is worth trying (at least for a couple of months you will get pleasure from the game)
2) although the game is updated frequently, it is unlikely to be new and cool.
3) you can play without donating and not feel like you are too far behind everyone else (although achieving the maximum is also almost unrealistic).
4) graphics for phones are at the highest level, for consoles and for PCs are above average.
5) there are many events, including cooperative ones, but you can’t expect much from the cooperative in this game yet (too limited).
6) and most importantly - completely free.
