I started playing it by curiosity and ended up obsessed with Tunic's adventure, it's a very fulfilling experience with lots of charm and challenge. It's a mix between elements of the Legend of Zelda with some "Souls like" mechanics and a very unique design and aesthetics that resembles classic games from the SNES era.
Intricate puzzles and exploration will keep you submerged in Tunic's world for many hours if you are willing to discover all of it's secrets.
