Title. Should I get both, or does Unlimited contain all of the standard version's content?

What are these gold doors? I have reached all three endings and been in the added secret room that appears after the train ending. The only obvious thing it occurs to me that I haven't done is break into the vault.

game looks awesome, I wanted to know if there will be Steam Achievements in the game, I really hope so *fingers crossed*...either way good luck with the game

Hi I was playing the game and had collected 60+ coins then I had to go somewhere , so I exited the game, when i returned the coins were lost, is this a bug or game feature or am I missing something.
