Hello there,
I wanted to add the cloud save function to the game for a long time, but since the current save system cannot be saved in the cloud, I haven't been able to add it yet. To add cloud save functionality, I first need to modify the current save system. And changing the save system can create major save problems and that's why I've given up on a new save system many times before. But now I'm working on it again. While I'm doing my best, no problems should arise with the new save system, but if there is a problem, do not start a new game, I repeat do not start a new game. Just let me know the problem and I will try to solve it as soon as possible.

Hopefully the new save system will be implemented in the next update and cloud save in the update after that if all goes well. Nothing to do on your side, your saves will be automatically converted to the new save system.

Thanks
