Rogue Legacy/Game Mechanics and Glitches
From SDA Knowledge Base
If a trick applies to only some versions of the game, note which ones that is.
General
-You can use the dash ability as you're entering the castle to be spawned a little further. You can also talk to the reaper while dashing and it won't stop the dash. -If you find bookshelves that are nearly touching the ceiling, those can be used to clip through. When you're OOB you might be able to access new areas faster.
