The simplicity of this game and its focus on the humor with the voice lines and dragoon animations are what makes this game so fun to play!
To make the gameplay feel more responsive, I would recommend making the reload and cover animations quicker, but also give them a few anticipation and recovery frames during the transition. This will help make the game feel snappy without making the animations feel instant. Also adding some more anticipation to the dragoon's firing would really provide more game feel to the experience.
I hope this helps! I had a lot of fun with this one :>
