It's High Noon
This is my PICO-8 remake of Ocean Soft's Highnoon, originally made for the C64 by Andrew Spencer and Steve Wiggins.
There are a lot more bullets on screen in my version and the gameplay is much faster. Also there are no abducted saloon girls in my game since they are all pretty much capable of defending themselves.
How to play: Waves

Use the D-pad or arrow keys to move around.
Shoot by tapping or holding the primary button or x.
Hold down the secondary button or c to keep firing in the same direction.

How to play: Duels
Wait for the games title plate to vanish and the 'Draw!' text to appear on screen and shoot quickly using the primary or secondary button. Shoot too early and you will lose a life.
Hints

Shoot outlaws early during the levels to get a higher bonus at the end of a wave in duels.
Keep moving around since outlaws will always shoot in your general direction.
You can exit the screen to the left and right to reappear on the opposite side. Use this to your advantage to avoid bullets.
From wave three onwards outlaws will throw dynamite sticks at you. Shoot the dynamite to kill outlaws.
Horses (wave 4 onwards) can't kill you but the riders might.

The Bountydex
In duels you will fight a variety of outlaws with randomly generated names and titles. There are ten special titles that can be collected in your Bountydex by shooting them in duels. Since it is a chance of like 1000:1 to meet one of these titles exactly there are two ways of unlocking these titles.
Let's take a look at the second item, the Blind Barber.
Now let's say you meet a Furious Barber in a duel and you shoot them. Justice in the Wild West was just a word and since you shot a barber, the item will be crossed off your Bountydex with one stroke even if it was not a blind barber. After all how many wanted barbers can there be?
Now let's say you got really lucky and you meet the Blind Barber against all
