so far I have written in a document that a crossover would go as such.
1) the game can be played solo or with up to four players total (two humans, two merfolk, one merfolk-one human, two of one type-one if the other, two of each).
2) there would essentially be two modes of play. Story mode, which incorporate the gameplay of Sunny Side bay where you journal the changing and growing relationship of the characters throughout a set number of years. Community mode, which incorporates the gameplay of Whoozits and Whatsitz where you go off and explore, do odd jobs, interact with your community in order to improve it.
Essentially as your relationship with your neighbor(s) changes and grows so does your community. Maybe by the end of it your town kinda becomes small and abandoned or maybe it grows into a tourist spot. Maybe the Merfolk are hidden from the surface and only isolate themselves more or maybe they extend a diplomatic hand. Both communities growing and changing together but independently.
I鈥檓 currently adding and changing tables from W&W to support this.
