First off, you only see that message when you die, so skill issue.
Second off, yeah the time to kill enemies is a little long, but the reloading is the way it is for a reason, it's supposed to make you be more careful with your shots and avoid spamming when you don't have enough ammo.
Thirdly, little animation is a stylistic choice.
Thank you for the feedback, I'm glad you played :)
