These days, I'm very used to the classic point and click adventure games being extremely short since most of the ones I consume come from flash games. The type of "escape the room" style games with a few unique ones thrown in there.
Based solely on this video, Olav and the Lute seems to have a charming amount of weirdness to it that gives it a very unique atmosphere, and I like the fact that you have to figure out some of the puzzles musically. Not just that you have to play a specific song, but that you might have to play it backwards to get the opposing effect.
Definitely going to give this game a playthrough now. I would have never heard of it if I hadn't seen it here.
