Neat project! It's cool to see more people getting into Godot. I loved the look of the environment you created. I liked the movement too, though the sprinting is a bit much for the small size of the map in my opinion. The mouse sensitivity was just a bit too high for me as well, but luckily still playable. The only "bug" I found was not being able to shoot enemies that are too close and clipping through the gun. Also just fyi, for some reason the itch app doesn't detect your game as downloadable/installable. Usually I've found it's because of it's strict folder/file structure requirements.
