The story is the two characters (alex and isabel) fall through a strange crack in the world after a storm, and they meet someone who explains that the multiverse isn't really a multiverse, but a two-part bikiniverse, and it is falling apart, and they need to collect the 124 power donuts in order to reunite the two halves, otherwise the BIKINIVERSE will become undone.
@sven I see what you mean. But I kind of like the weirdness of the name (kind of like goat simulator, shower with your dad, etc.) and how it isn't what you'd expect. People who like bikinis are likely to click on it, people who think it is "creepy" are also likely to click on it to see what it is. Also, I want to put many funny jokes in.
The explanation of the game on itch might be something like:
Welcome to the bikiniverse. Alex and Isabel move together. Get one of them to the donut, don't let either of them fall into space. Despite its racy title, this game contains, disappointingly, no nudity.
