YMMV / Mermaid Swamp

  • Insane Troll Logic: Uri's games have a general trend of forcing you to choose the LEAST realistic option during a choice scene in order to get the best ending. In Mermaid Swamp, you have to NOT light the fireplace in Yuka's room, despite her constantly saying how cold she is and the game neatly handing the firewood to you. You also SHOULDN'T dodge when being attacked by Seitaro. Justified in the case of the latter, as he is under the control of the mermaids' curse.
  • Nausea Fuel:
    • The description of what happened to the legendary mermaid who was kept in a tank.
      • ...and the fact that the legend was based on the Tsuchida family's fascination for keeping young women in tanks of water.
    • When a starving Rin gets desperate and eats the flesh of one of the "mermaids".
  • The Scrappy: Rin's dialogue mostly portrays her as a whiny, spoiled and mean-spirited brat, that it's difficult to like her and she's the player character. Though she does eventually show more of her Jerk with a Heart of Gold aspects, making her less annoying.
  • Squick: There are sound effects when Rin accidentally overhears Yuuta...doing things. What makes it worse was that Yuuta was thinking of Yuka. Yuka in her current swollen condition. And more disturbing still, his sudden strange fascination with Yuka mirrors that of the Tsuchida family and their reasons for sticking young women in tanks of water. And also, Yuuta was Not Himself and not acting of his own free will entirely. Yikes.
