Holy shit dude nice job! I can't believe you were able to do this all by yourself.
The design, the lighting, the set pieces all mesh really well and are incredibly polished. Your game definitely stands out.
From a gameplay perspective, it's kind of weird that your player is immortal so there really isn't any need to swing the sword. Also would have preferred the attack button on mouse click. I'm not accustomed to pressing F with WASD controls. But these complaints are completely minor especially knowing that you only had one week to do all this.
