Oh wow, this game is old, i’m not even sure anymore haha I think the friend code refreshes after some time and you can use it again. You just can’t repeat the same code over and over
It’s not a real time PVP, so even if you win on your side, the other person can also win on theirs =P But feeling like you always win if you input the code is actually just coincidence, there is no difference on that. And, no, this is not in development anymore. It was my first game ever back in 2019.
