Those heads following around were definetely unlocking a new fear in me. I sadly could not do anything in any room I entered. So from a game design perspective it would have been useful to make the game a bit more streamlined, e.g. by ensuring that the player gets a core-set of abilites. However: I do understand that considering the vision of the game, adding more hints would sort of destroy the vibe of being lonely, tiny and meaningless. Personally there could be a bit more stuff going on in the environtment. Just because the game is about mega-structures it does not mean that there cant be small stuff going on. I would even claim that having a bunch of small elements and world details can pronounce the massive environment and therefore improve the world-building. Atmosphere wise that game is great, especially considering how minimalistic the surroundings are.
All in all: cool game, but some support for the player would have been great.
