Good graphics, needs some improvements in case of shadows.
Something wrong with picking of the weapon. Maybe better pick it up with a mouse click.
Good ambient music.
Hitting need some improvement or feedback - it missing clicks and player does not know why hits so slow.
Movement needs some twicking. It feels like a bit uncomfortable using WASD, but clicking with a mouse it rotates and moves player softer.
Game seems like a casual, so it needs some steps into casual style of UX of controls.
Great job!
