Possibly one of the final major content updates before full release, adding:
A new map type pictured above
Ambience and musical melodies, aimed to be as minimally intrusive as possible
Score system
Difficulty system
Leaderboards
UI tweaks
Better and dynamic train path line visuals
The score system is influenced by the newly added difficulty system, where you can tweak the difficulty to be basically trivial or completely imbalanced - your choice! The difficulty you choose to complete the map will determine the score multiplier, which ultimately ties into the leaderboard system and how you rank compared to others.
