Through Abandoned: The Underground City

Through Abandoned: The Underground City is the first game in the Through Abandoned Trilogy. It follows the path of Steven Tsar looking for his brother.

Plot
On June 28, 1904, at 20 years old, Steven Tsar goes to a hotel looking for his brother, only finding a note reading that he should go to a location. At the location, Tsar finds a mysterious door that leads to an underground city with a mine cart and rubble blocking the exit. After solving a puzzle to make the mine cart crash into the rubble, Steven goes into a big, open, underground city. After finding four light bulbs, he gets a code that he uses to go through another door that has a doorknob. The doorknob leads to another door, which eventually leads to The Forest, the main area of the second game.

Secrets
The Underground City has four secret letters that lead to secret notes at the end of the game that are for lore and also a message from the developer.

# 1: The fifth light bulb stand after you get through the rubble is a shade of brown and cannot hold a light bulb. Clicking on the bottom will lead to the secret.

# 2: Just before the cube puzzle clicking on the block on the right side will create an opening that you can look through and get the secret. The opening shows the big flower from the well.

# 3: Just after the area where you find the code from the light bulbs, there is a vent. Going one tile down leads to an area where you can use the pickaxe to break through on the left side, leading to the secret.

# 4: After entering the first door, going up the ladder and stopping just before you reach the area with the matchbox, there is a crack in the wall on the top-right corner that you can break with your pickaxe leading to the secret.

Getting all four secrets will unlock a door in the white room that will lead to four notes left for you by your brother (and one from the developer depending on update) relating to lore (or a message from the developer).
