We've optimized the sound of trains running. (The Port of Trena is still under construction.)
Adjusted the balance of rail joint sounds Previously, the audible range of the joint sounds was too wide, making them sound like a loud noise. Therefore, we've adjusted the balance between distance and volume to make the sound more realistic.
The latest trial version has also been released.
We'll continue to update the game, so please let us know in the comments if you have any questions. Thank you!
