5 stars: Stunningly beautiful and aesthetically pleasing pieces of artwork. This is without any doubts the best mobile game I have come across, allowing you to be casual while staying relevant and giving you enough options to progress without paying a penny. Lots of heroes with a lot of different skillsets, this game makes for a refreshing experience and a worthwhile adventure! Highly recommend giving it a try!
4 stars: Crashing every minute. Please fix. I really am disappointed that you make updates as fast as you can, but not handle simple problems.. Edit after the hotfix/update (16th September 2019): I can feel the update made it better. There's still something that crashes it.
4 stars: Ive never been able to see/send IMs. I can access and post to the global/english/guild chats just fine. When someone tries to message me, I get a notification on my phone but upon opening the app, nothing is there. When I try to send messages to other players they never go through. This has become frustrating as I'm a guild leader and people try to contact me with questions.
5 stars: This is a wonderful idle game. 1-2 checkins per day is enough to make good progress in the first several months. Moneitization is not too aggressive, and there are ample opportunities to earn premium currency for free. However, if you expect to compete at the top of PVP, you should be ready for a very long, expensive grind.
5 stars: The game is fun, i dont know what more you would like to know. ...
