About Help! I'm Turning Into a Mermaid!
Help! I'm Turning Into a Mermaid! is a story-driven game about Hunter, a new conflict de-escalation officer at the Axon City Police Department. Hunter is not allowed to carry weapons, a rule that clashes with their partner Ember, a fire elemental who usually deals with problems by throwing fireballs. As Hunter investigates a conspiracy involving corrupt government officials, a cult of mysterious witches and militarised pirates intent on destroying the city, they also begin slowly transforming into a mermaid. The story spans 10 chapters and has a script of over 350,000 words.
Puzzles and jobs
You solve riddles, combine inventory items and operate complex mechanisms across more than a dozen interactive puzzle sections inspired by classic point-and-click adventure games. You can also take on job simulations: work the trade-in counter at Zara's Games, distinguishing real games from bootlegs, or cook four meals at once at Soupa Noodles while an impatient manager yells at you.
You can manage a Coffee Shrine franchise by assigning staff to tables and renovating the store. Explore the city and complete bonus objectives to recruit new characters to work there.
Relationships and choices
You can romance one of four love interests: a catgirl scientist, a male catgirl, a steampunk catgirl scientist, or Ember, a fire elemental who is sometimes a catgirl. You can also shift Hunter's alignment along the mutually exclusive Cute/Sexy spectrum to unlock different outfits and change how they interact with characters.
A new starting point
The game is a standalone story set in the same universe as Max's Big Bust - A Captain Nekorai Tale, Alluna and Brie, Max's Big Bust 2 and My Mad Scientist Roommate Turned Me Into Her Personal Robotic Battle Maiden?!? Knowledge of those games is not required.
