This is another complete restart, this time with better movement in the first prison cell and more precise angles to ensure maximum speed. It also changes to using right angles in the first brown room you need to turn in; I am not yet sure if this is the fastest possible completion of this room.
One note about the first room: At timetick 11102 as the first prison cell fades into view I send dy=70 (mouse force maximum to direction +y/east), then let go around timetick 11144; at 11230 the player's speed reaches value 45054, then on 11244 speed is 0, then 11258 speed is 14999 until I hit the door at timetick 11344. During the time the speed goes to 45054 and back to 0, the player seems to lurch forward in the room. This is significantly faster than the previous WIP, and appears to be a bug in how the mouse movement is interpreted when the fade-in happens.
