Legitimately caught me off-guard with how fun this is to play! Using your gun to not only float but gain height everytime you shoot, then slamming down on your horse when a bullet gets too close. I enjoyed this a lot! The animations you put in also really really sell the movements well.
My only recommendations are to maybe add some slight screenshake when shooting/hurt/slamming, and add a dedicated reload button so I could have a full revolver between waves of enemies.
Amazing work!
