Due to a bug with how the timer was programmed in game the timer would run at different times depending on how long you had played. After around 75 hours the timer would double in speed making the game essentially unplayable for speedrunning.

This has been fixed in the most recent update, now the in game timer runs at real time regardless of your stats. The board times have been adjusted for this and any future runs will still use the in game time. It's just more accurate now.

The game also now supports miliseconds.
