Bloodstained: Ritual of the Night

• There is a teleporter location directly above the hub in the village. You access it by exiting the village to the right to the screen that has two bone throwing corpses then immediately exiting to the upper left on that screen.

• There is a poorly telegraphed quest in mid game where the triggers to have characters explain it you are so easily missed im just going to spoil what to do.
  After beating a boss fight consisting of two dragons, descend the tower and collect the item in the gold chest. With this item, return to the room in the village hub with the nun and have your photo taken in the portrait studio. With this photo then return to the librarian in the castle and hell make you a pass for the train.

• If you're late in the game there is a suit of armor you can find that ignores spikes. You dont technically need this to beat the game but very late into the game there is a corridor of spikes you need to traverse and this is the by far easiest way.
