- Most Annoying Sound:
- The buzzer noise that plays when you input an incorrect puzzle solution or push a button on a non-working machine. Some Let's Players have called it the "sorry noise".
- Some players aren't too fond of the 4th game's menu music, since it not only consists solely of a high-pitched tone repeating over and over, but it plays every time the player accesses any of the menu screens.
- Narm: The games are laden with this, but get better as the series goes on. Kales in particular mostly talks in a bored, monotone fashion, and only appears in text in the first game.
- Nothing Is Scarier: Rhem 2 can feel like this, with slightly unsettling noises in the background that sometimes sounds like footsteps. Doesn't help that the Lady in Red occasionally walks past in the same areas.
YMMV / Rhem
