Platform(s): PC
Genre: point and click, puzzle game(?), possibly horror?
Estimated year of release: early 2000s, maybe 2010s
Graphics/art style: 2D pixelated style. bright colours
Notable characters: MC is dressed in a gaudy way iirc? there's a hotel receptionist you interact with, and a person who you kill at the end of the game
Notable gameplay mechanics: the MC only exists because the NPCs are looking at them. it's the whole gimmick of the game. the MC basically stops existing all together after they kill their target. it's pretty short
Other details: i remember hearing about this game from a youtube video a good few years ago. i thought it was super cool and only recently remembered it. looking it up isn't helping because of how little i remember from it.
