This was amazing. The music and visuals were great, especially the lighting. The controls felt good to me. While I did die a lot, at no point did I blame the controls. From a technical perspective, I felt like it was VERY polished and well tested. As you saw, I got a little stuck a couple of times there, but that's just part of exploring/adventure games like this.
The final boss was exactly as difficult as I wanted it to be. Yeah, it was hard, but it wasn't impossible. I had to learn its attack patterns and when I did defeat it, it was awesome.
YOU ROCK!
