I think the achievement for beating it in 25 minutes needs some updating. I paused a good amount on one playthrough and ended up getting 45 minutes. This is after beating the game 4 times and on my last playthrough getting 28 minutes.
So basically, pausing the game takes up time I think. That or quitting out and starting back into it erases the pieces you placed, but saved the time you left it.
EDIT: If you dashboard it seems to be the safest thing to do. Pausing takes up time.
Route C is the easiest to beat for time. Did it in 21 minutes.
