Nice starter game! One critique I must give you is about the control scheme. Currently, with the way you have the controls set up, there is no comfortable way to position your hands for movement, jumping, and aiming/shooting all at the same time. Try making the spacebar jump, so we can use it and WASD for movement, while keeping our other hand on the mouse, or maybe add the jump button to right click on the mouse. Whatever you prefer is fine, as long as the player can press all the buttons that they need to at any given time. Nice job still!
