Thank you for the feedback!
Concerning aiming and shoulder switching, that seems to be unanimous so far. I will sort those two issues out for the next public build.
The chain extends all the way to the next ring, which may not be obvious right now in the current state of the game. I plan to add schematics and animations to make it more obvious in-game.
On your comments about movement, I'm taking notes. There's a lot of work to do still. Same thing for the shaders and models.
