Epiphany accompanies the most seductive of illusions. -3 Corinthians
A very purified puzzle adventure game. Minimal narrative. You explore a lovely island in a free-roaming manner, and engage with deceptively simple maze puzzles. That's the one basic method of interaction with which to unlock doors, operate mechanisms, and otherwise make progress. Connections are made on multiple levels.
If you get frustrated, I recommend perseverance. Take a break and come back later.
For anyone who likes challenging puzzles, stop reading about it, don't watch any videos about it, just play it.
