As mentioned before, this level (so far) is not too unique, but these are the things that stick out:

The Robbery

The room above the cashiers/vault is home to two characters seen trying to saw their way into the gambling earnings. This area is special mainly because you can use it to get into the floor below. To do this, throw something at the slightly discoloured floor piece to give way to a square shaped hole. This will allow you to jump down. This room also has the characteristic of starting the riot when you walk inside it, and the two enemies will only attack if provoked, or the total enemy count is low enough.



A funny attention to detail is that if you look closely, you can see the sawdust trickling down on the floor below.





Something else I also thought was pretty amusing is that the piano player will play his music during the riot with the same aforementioned properties, but if he is provoked, the piano will play from a recorder, and will also sound different.

The Goon

Directly at the back left side of the saloon is an enemy that resembles the giant inmate from the prisoner riot level, with what I believe is pretty much equivalent stats. Just like the robbers, this character won't attack unless provoked, or there are few enemies remaining. There is no penalty for walking near him.

The Safe

In the back of the cashier room is a safe with a revolver inside. A new weapon featured in a release like the last two (shotgun, and flintlock)
The revolver has no special characteristics really. From what I tested, it seems rather incapable of penetrating through several enemies, but nonetheless is a fun weapon. To get into the back room requires using the aforementioned strategy, or alternatively, hitting one of the cashiers through the bars, in which they will open the door to attack you. You can wait until the enemy count is low enough too, but that kind of defeats the purpose of acquiring the gun in my opinion.



(Many thanks to JustAGamerPerson for letting me know about the first method, which I originally missed.)

Beneath Symbol

One more little thing worth mentioning is the hidden beneath symbol inside the fireplace. You can only really look at this by taking damage, so it's not really practical to investigate. Apparently it can glow, too, but as for it doing anything, I think it's just aesthetic. You can see for yourself.

This level has a few deadlier weapons laying around, mostly scattered around the map around two being on enemies, such as:


And another one having a mop nearby.


as for the weapons found around the map:























(Note: You have to jump to see some of them.)

And that's it. Overall, I don't know if I have missed any secrets. This seems to me a slightly WIP map, and the devs have stated that more will be added, so I will add anything retroactively. If you have found anything also and I deem it worth putting in, I'll add it and credit you. Thanks for reading.
