Please read before you comment. So I have checked some issues that I found in some of the comments given below. I managed to kind of getting to the game and I could provide some help regarding the problems here. First, let me start with the installation. Right after you install the game, you have to put the obb file. Just in case you dont know about it, u have to put it in folder android- obb. some people may have problem like error when entering the game. here, make sure u put the obb correctly. check in the obb folder again. check whether inside the game folder, you dont have any other folder. in kther words, right after the game folder, there should be the obb file. you may duplicate the folder when extract the obb from zip file. check it again. Second, about checking the system etc. I noticed that some people may stuck here. For me, there is no problem here. I believe it is may be caused by Internet connection or maybe the game is just to "hard" for your phone to handle. Try to clear your phone from trash etc and make sure your Internet is good. Third, it is about using Facebook to login. I have no issues here. I dont have FB app in my phone, so i use my browser to log in to my fb. after that i get to the game and chose Facebook to login. then i see my fb name in the game screen. after this, the game will restart and u back to login screen again. dont panic, just hit fb login and u will see the server screen. it means u have successfully login to the game with your fb. the next problem covers two issues, menu mod does not appear and you cant pass the tutorial. listen up, you cannot pass the tutorial because the dmg and def multiple are set to 1. in order to pass the tutorial, you have to chance it. mine is dmg 2 and def 5. if you did not do that, then u will hit the monster forever and u get one hit killed by them. that's cover the unable to pass the tutorial. so now, u have to have the menu mod. just i case your menu mod is not showing up. go to setting in your phone. try to figure out which settings deals with permissions and so on. in my case, i use redmi 5a. i open the setting, go to permission, other permission, then check the permissions of display popup window. make sure the game has access to it. for this problem, u gotta find the permissions setting and that's all. I dont really into the game so i just open and played till i finished one or two stage. well, everything is fine with me. i deal with those issues as well and i managed to solved it. hope it helps you with your problem. cheers.
