I solved it without using a single clue. The most annoying puzzle was the last one because despite knowing what to do the lyrics were really hard to find. Anyways, the last one brought down the experience for me, but as a person who typically can be stuck in puzzle games for a while, I never had that problem here aside from executing the solution. The text at the end cut off, so I didn't know what it said. Also, making the lore clearer could also be good.
