I don't know if i was the only one to have this issue but the image was kind of stuttering, when moving it was even more weird, like i had the previous frame right before each new frame, it made it a little harder to follow the movement.
Otherwise i like the idea of charging, though i didn't really saw the point here, as charging only throw it a little further and faster, it won't help you kill more enemies that are aligned (which is a shame because it would feel great) plus the further the bullet goes the slower you can shoot so the game actually makes playing close to enemies better.
Though it is quite intense to dive in a swarm and try to avoid everything, i beleive charging should help you make your bullet pierce through enemies, or it could make it bounce off objects. Some slowmo when close to a lot of bullets/enemies could be cool too.
The controls felt pretty great, would have loved a bit bigger level, doing some parkour while trying to dodge hoping for your bullet to catch up would feel amazing.
Lastly i would recommend to do something to be able to differentiate the projectiles, like some color or else to know which follows you and which don't.
