Well, I learned something today! Granted, my musical education stopped after high school, but I've never stopped playing. I have never heard of or seen the c clef before. I just fell down a wikipedia, Google rabbit hole on that topic today.
Similar issues as others have stated, didn't realize I could go under the bridges, and I started to panic that I was a dense player on how I was going to get that note all the way on the right of the first map. I was wondering, too, if there was something to clue the player in that it's now time to insert the bass clef or c clef other than they were recently collected.
Pretty music and background sounds. This is probably the best game I've encountered so far using the musical interpretation of "scale."
Does this make you want to play Loom again - it makes me want to play Loom again.
