AmogOS was funny.
The groaning sound coming from another room is scary. The anticipation of what will happen is scary. The actual jumpscare is not scary at all and takes away from the anticipation and confusion of the groaning. The game was at its scariest when I was walking to the garage and heard groaning from somewhere and it was at its least scary when I saw one of the monsters running at me after the groaning stopped and I knew that it was just a mini jumpscare.
The objective "Get pills" is a bit weird considering I already have pills. Maybe you meant to say "Get more pills"?
The atmosphere of the game is fantastic, I love the foggy effect. Even though it was probably done for time, the simplistic untextured geometry kinda helped to give the game a dreamy surreal feel.
One more thing, right-click for interact is a weird choice but it's an actual problem when sanity pills are e. It's very common for games to make e the interact key but now it consumes my pills. I accidentally consumed pills multiple times while trying to instinctively open doors with e.
