Hey, thanks for playing and for leaving such detailed feedback!
Addressing readability on the guns and fixing up their sounds is one of our bigger priorities at the moment! A lot of people don't realize that weapon you find in The Mall is supposed to be a sniper, but this, like many things happened due to time constraints and we are working on hopefully fixing it in the next update! Tracers is another big one I've been wanting to add, even though the weapons are technically 'hit scan', that would be a really good way of giving some feedback on the aiming. Particles hitting enemies is something I want to add as well, hopefully striking a good balance in the process.
The Mall struggled from a lot of over ambition in not a lot of time. It's getting a complete re-work as we speak to make it more in tune with the rest of the game.
I like the idea of a sniper enemy quite a bit! Difficulty and balance are two things we want to address, I'm hoping to give the AI a whole polish pass and maybe implement some kind of path prediction to enemy projectiles.
There's a lot I plan to do to clean up junction points. The major issue you're referring to is an easy fix because for whatever reason I had the grapple still check if it's valid while the grapple animation is playing. I'm going to spend some time converting this so that if the animation is playing, the grapple will attach even if you fall out of range.
More gold source movement is on the way! We're currently completely re-writing the character controller.
