Thanks for the feedback!
Recoil is one of those things that needs to be both tweaked and better communicated, to be honest. I totally get that frustration.
Regarding slides and slow-mo, I share your points on this. They were implemeted extremely early in the prototype, and now they need more refinement. I'm not happy with the fluidity of movement (hotkeys, behaviour and overall utility), so I'm planning on making some very important changes in the short-term. I also have an additional change planned for slow-mo that should make it feel a lot better.
But again, thanks so much. I really appreciate you taking the time to try this out.
