the world of Shima no Shima began a few years ago with a single goal: i really wanted to see manga/anime-style rain in a 1-bit game, and i hadn't seen that done before. i had no idea what the story or setting was going to be about at the time beyond that.
i was a bit intimidated by the prospect of coding weather effects by hand in adventure game studio. it took me a few days to come up with something similar to what you'd see in a graphic novel.
the little hypercard "weather control" window on the bottom right is part of my game development tooling. i can set the appropriate weather for each room in-game by dragging each slider, and seeing what it looks like. when i close the window, it saves the weather for that room. the weather changes dynamically during gameplay as well.
