Glad you enjoyed it!
There is a gallery system, which I named the memory system. It's available through the in-game menu.
There also is a settings menu. Or was there a particular setting you were looking for?
Both are accessible through the in-game menu which is opened by pressing either the "X" or "0" keys.
Adding saving everywhere will likely not be added, as it can cause some various issues. But the other two things you mentioned are already there. Now go on, buy the game 7 times!
