Love the idea of a whole-ass Game Boy game. As someone who actually had a Game Boy (yes I'm old), this really hit close to home (heh). The visuals were serviceable, likely better than a lot of devs would have been able to make on the Game Boy back then honestly. The horror was slightly undercut by how gosh darn adorable the monster sprite was, though. The story was short but sweet, nothing special to it, but I especially liked the meta line at the end, implying that the player is now haunted. Very creepypasta-like vibes. I suppose I would have liked if the text scrolled by a bit quicker, especially on the chatroom. The roommate's dialogue could also have used a tag to make it clear she was talking. And the MC acts a bit oblivious at times, which makes this a very tropey horror, but I suppose that's the point. I'm aware that the time limit probably played a big role, but I'd have loved to see more gameplay from a Game Boy game, since the only thing that's actually there is mash Z to continue. Even just moving from room to room with left and right would have been nice. Well done, regardless, since this can't have been easy to make from scratch.
