The intro cutscene and general aesthetics of the game are weirdly charming to me, like they're straight from an old CDrom game from the 90's. I really liked them.
Gameplay-wise, I think there's inherent satisfaction to watching the map layout unfold in real time as you progress through it. However, the way it unfolds is a little slow... I personally would have found it more satisfying if the echoes happened more frequently, and had a wider range. It'd reduce the 'difficulty' of the game, but I don't think the game is really difficult to begin with, just time consuming.
