Don't know where else to post or if this will even get to the dev but whatever.

Quickswapping from the shotgun to another weapon while the shotgun is doing its "Spin Reload" will transfer the spin animation to the gun you swapped to, messing with the projectile path of the grenade launcher, and probably the Leech(?) launcher. The projectile movement seems to be based on the gun's orientation, so it's possible to shoot behind you, or above your crosshair as there's a little bounce at the end of the spinning animation. As cool as it would be to master this, it doesn't feel intentional and can mess with regular gameplay. I would like to see the spin animation transfer be kept if possible tho, I like it.
The spin-transfer does not mess with hitscan weapons and the laser gun, which shoot where you're aiming regardless of gun orientation.

And quickswapping in general could feel better, the guns have very similar shapes and colors (especially in this dark demo level) and its hard to visually understand that you've swapped weapons sometimes. Idk how to improve it or if it even needs to be improved, just leaving it here.
