I liked the tracing minigame, that is not one that I've seen often. However, I had to stop when I got to the door that has a squarish tracing rune on it. when I traced it the door wouldn't open up, I wasn't sure if I was doing something wrong or if I just wasn't supposed to be there yet
even simple sound effects go a long way! some ambient music or noise would have been good as well
interesting idea overall, nice work!
