Hey there
Thanks for the feedback - it's always welcome. This is an asset, not a game atm, so bug fixes and extra options benefit all its users.
I'll look into point 1. I just reworked some of the keybinding, so I might have fixed it. I wasn't explicitly looking for that though. Will have it tracked down shortly if not.
2 is definitely doable. I've done similar for an integration with an asset for picking up scene objects. I'll add it to the list
3 I've fixed. I'll get a new build uploaded tomorrow with that fix in, along with some extra polish features.
I agree with 4. In part that's the animations of the baton. I need to do a full rework of the melee system though and expand it to match the firearms for features. Aiming for something along the lines of Vermintide 2, but I have a number of larger features to sort before I get to that.
