Great job on your animated graphics and background music on main menu and excellent HUD integration. The environment felt thought out and consistent with a clever animation for breaking through the walls to proceed to the next room. Being someone who grew up on console games of the 80s, and still opting for console vs PC as a player, it's a preference for me to have a camera follow the player on a PC game rather than having to use the mouse, but that's just feedback from an older generation player. I appreciated having the sound effects as well as the graphics for when the enemy was killed. One suggestion would be to add a health bar over the enemy's head to give feedback that you are hitting the target and inflicting damage.
