This game is well-written on the line-by-line level or even scene-by-scene but doesn't know what it wants to be. It starts out seeming like a promising kid's fantasy, then changes to a bit older (you're told that all the patrons at the science society are hot and get divorced all the time because of it), then into more slapstick comedy, with some magical adventure thrown in.
The main thrust of the game is that you saw mermaids as a child and want to join the Marinological Society to study them when you are grown. You need to pick a patron to support you (and the game informs you that patrons are often romantic partners), then you go to the island to look for evidence of mermaids.
Parts of it were actually pretty great and/or funny, while other parts were a bit more weird. Instead of skills you have only opposed stats, and once you pick a patron if you want to please them it determines a lot of the choices you have to make.
There were some big choices to make near the end, and I ended up alone and sad, but at least I kept my promises.
