Thanks for the awesome feedback!
I'm going to be adding some indicators that help with conveyance on reason for death. It's extremely confusing at the moment so sorry for the frustrating experience.
The knife hand being stuck if you swing too early is by design though, so that's a penalty for not timing the swing properly. I know this can be annoying because it's very much unlike how other FPS games include melee.
That mouse being frozen is the truly annoying part, let me see if I can fix that up. It's a real pain while I alt-tab during development too!
Thanks SO much for trying out the game and the detailed feedback! Working to make it better 🙏
