I think the GMTK-Jam has an ongoing joke about everyone doing "shoot to move" whatever the theme is, but you found a creative new way, that I haven't seen before. I could totally see this being streamer friendly hit on steam!
The reloading mechanic doesn't add much to the gameplay, and maybe you can look into creating more loops in the level design, so if the player fails a jump, he only drops to an early level.
All in all very promising!
