Great work on your game! Made it to the third level, which was really dark and the camera kept swinging behind walls, so it was very difficult to navigate. There seemed to be a bit of drift, so aiming could be tough, but maybe that's just me.
One thing I would have liked is the ability to hold down the mouse button to keep the bow drawn, maybe with a timer for the stamina of the character or something, just so you could release the button and fire immediately without the animation delay
