While the movement interaction system was far from intuitive when it comes to moving towards and away from any given thing. I will forever be accidentally exiting the thing I'm looking at. However, the game itself is incredibly well done. I will have to play the VR version now as I felt many times that it was designed as game that would be even more engaging within the VR space. The puzzles span a lot of different styles of critical thinking, although some could use a bit more in-game explanation for generations that may not have ever encountered this kind of thing. I know that the suspense is intentional, but for me it was negative and caused undue anxiety by way of how calm and studious the rest of the gameplay is. The seemingly random and unpredictable loud and creepy feeling of the invisible antagonist felt more in line with what one would expect from Total Mayhem Games, but it never truly manifests as a true threat. All in all I would thoroughly recommend this game, especially if you enjoyed games like Myst or We Were Here...but with an alternate historical slant and no dying. Kudos for the inclusion of replications of legitimate DaVinci drawings and recreations of some of his inventions.
