Right off the bat I will say, the game says it's online, it's not. It's single player only and can be filled with AI's if you want it too and you can have them join your party.
However, on attempting to cheat this game myself (not proficient at cheating aside from basics and reading addresses) I noticed the game has it's own cheat detection and ban feature but it is easily bypassed by not logging in (has cloud saving) and deleting the save data (com.abiss.roem -> files -> data -> data.roemdata) should you be banned. I have done this many times and it works great for modifying values without risk so I was wondering if there was a way to get pass the cheat detection and make changes permanent.
[I am going to assume that logging in, using the cloud save function (tied to abiss.co servers), and modifying in-game values will ban you permanently with no chance of ever being unbanned]
Perfectly fine with anything, I know speeding up time (no time-skips) works fine and isn't caught by cheat detection but if you use it on a real save game and use two different phones (bluestacks and galaxy 9+) one save will be days ahead of the other and you can only use cloud save every 30 minutes which you will never be able to reach unless you stop using the speed hack.
I have been using Bluestacks for Game Guardian use and my Samsung Galaxy 9+ for regular play (because I got the Snapdragon variant).
I also find this Korean game's poor translation to English really funny, they are brand new to the play store as they have only been on it for 3 months.
