There is a new update for LIBRARY that includes a speedrun mode. To enter speedrun mode, press G after clicking LIBRARY or Morning Post. This will restart the game in Speedrun mode (indicated by a timer appearing on the top left.) The timer will start on first input.

Any% will now be using only this timer! All Kids and All Achievements will also start with speedrun mode, but you have to use an external timer (livesplit) as the in-game timer will stop after reaching the end of the game. I hope you all have fun running LIBRARY!
