First stage route is extremely improvable and affects routing/strategy for the rest of the game.
The Minnie kidnapping recovery 'minigame' always deposits you on the bottom left corner of the screen. There are two possible places this can be used to save time.
See green arrows. The left is a huge save on the way back, the right is (likely) a minor save on the way there. Note that this makes it much less of a detour to collect the second weapon so will probably save time later to do so. Also, route on the way there (killing the cat) will probably need to be modified, and Minnie's presence both saves and costs time in different places, so some thought has to be put into the best spot to get her kidnapped.
Note that deaths behave the same way, but getting hit that many times takes forever.
