Hey everybody, thanks for trying the map! I appreciate that!
I should've posted a tutorial since I assumed some people would get stuck (My bad). This is my first map!

Here's the walkthrough:

1) Go behind the bar and read the note stuck into the column. The note says to look at the cups on the shelf behind you and look for a key inside one of them.
2) That key unlocks the small chest in front of the previously mentioned shelf. Inside will be a note of what you are supposed to be doing (putting the sea monster paintings in the right order).
3) Around the bar, you will find various notes detailing different puzzles. One is to find a throwing axe to throw at the board near the back of the bar, two others are to figure out the combos to a couple locked boxes, and the last one is to clear out some spiders to gain access to the back room.
The Throwing Contest:
There is a chest located in plain sight underneath the throwing board located immediately on the back wall. The note attached says you need to find an axe to throw for a challenge. The axe you need to find is located behind a barrel to the right of the entrance. (Looking at the entrance). You'll need to move the stools in order to access it. After grabbing it, head to the back pair of columns and the board will have an image of an axe imbedded in the board. Click then to solve the puzzle.
The Poker Game:
There is a note underneath a chair behind the large circular table, reading it reveals that a cheater rigs a 4 Card Poker game. It details how the dealer always gets a perfect hand while leaving the other 2 players with only a high card hand. The logic here was that poker is played starting from the left of the dealer, so that's where the code for the lock on the same table comes from. Reading the cards in terms of the values of the cards them selves, it will be 6, 9, Ace. The code is 691.
The Second Box:
The way to start this one is to find a note in the right hand corner of the tavern underneath the large table. The note contains a circular maze that contains a code for the lock. The maze starts near the bottom right. If you follow the maze, from the entrance to the center, the code will be 357..
The Spider Infestation:
To start off, the owner left behind a note on the left door of the first shelf. Open it. and you'll see what he has to say. Around the bar, there are 4 spiders lurking about. Three of them do nothing whilst one of them actually will give you a code to the lock located on the door behind the bar. This spider is located on the leftmost barrel high up on the left wall of the tavern. The code it provides is 428.
4) Once you have completed a puzzle, you should find a note within some sort of chest or container that opened nearby. When reading the notes, it will detail which sea monster was supposedly discovered in which year.
You must put the proper paintings in the proper order from left to right, starting with the earliest "discovered" creature.
The order of the paintings goes like this:

1) The Great Maw
2) The Sea Horse
3) Sarmation Sea Snail
4) Beast of Bubrovnik
5) Gloucester Sea Serpent

You MUST finish all of the puzzles and put the paintings in the right order to finish this room.
Usually you have to finish all of the puzzles in order to get the notes the figure out the order of the paintings.

Sorry for the confusion and thanks for playing!
