I played it on stream if you wanna go watch the video on twitch. My personal qualm was mainly with having to hit the button again even after a reload. I kept forgetting to do that part. I like the idea of a more involved reload system in a game I think just making it slightly more intuitive would help.
I also thought it might be a fun side thing to add the ability to spin the barrel with mouse wheel (maybe this could even be what you do to finish the reload instead of hitting the button again) and the barrel would animate but thats just me being extra.
