So first, a disclaimer. Because of the episodic nature of the game, and because this is The Last Door: Season 2, I strongly suggest you go to either the website or Kongregate and play The Last Door: Season 1. It's not the most necessary thing in the world, but it'll fill in the blanks as to Devitt, the weird eye motif, the Four Witnesses, and the secret society known as The Playwright. While the prologue chapter can answer one or two of the questions, a lot of them will be answered by just playing season 1.
But with that out of the way, if you're looking for a surreal horror game with a ton of atmosphere and a lo-fi aesthetic that manages to play perfectly with the player's imagination and delivers old-school adventure without all the pointless death, you need look no further
