Fun.
The Deadeye perk is very broken. Once you get it you can spam or use an autoclicker on a target's bullseye to gain a huge dps advantage that can carry you through to the end of the game more or less. This is even more powerful with ricochet bullets, as you can shoot a stationary target to take out vultures and bandits while they're moving. To balance it you could make it have a .3 second delay between perk activations.
I also came into this game thinking the first part was going to be the full game, almost like a shooting range incremental, which I was looking forward to. Following the boy was still an interesting concept though, but I'd love to see that first part fleshed out as it's own game. Similar to The Gun Game 2 if you're familiar.
Also the "Toss" perk under the "Tricker Shooter" job causes the bandits to walk sideways/upside down when they land.
