Thanks a lot for the feedback!
We hadn't noticed issues with the camera in playtests until now, but that may be because the previous map didn't need as much paying attention to your surroundings. It keeps its orientation relative to the locomotive, but that means that as the locomotive turns, the camera does too, which may be frustrating. I'm hesitant to completely remove that behavior though, maybe a toggle option in the hud would be best (even if it's not super elegant).
WASD and arrow controls are available, but we added them more as a fallback because we like having to actually pull the levers. We don't want players to default to the keyboard controls, so we don't show them, but obviously that's a super messy way of handling that. I also understand that it conflicts with the camera. Maybe a more clearly delimited camera-dragging area would work? Or maybe you're right and we should just let go of the lever controls. hm.
As for the beginning area, we hoped that the station would be eye-catching enough that it would be obvious as a first objective, but obviously that wasn't the case for you. I don't like being too direct with instructions on what to do though, so I'll have to find a way to make that clearer.
Thanks again!
