EDIT: Solved
Put in quotation marks because, from what I remember, there wasn’t much ‘game’ in it.
It was mostly just a bunch of characters (Male-leaning but there were still a good chunk of girls girls) that you could pick from and have them be big on screen along with other characters in front of a background that I think you could pick the color of, but was white by default. The style was top-down, and the expansion was entirely spherical.
I’m also pretty sure there was a gacha where you could randomly get characters, but I believe there was also an option to just get all the characters at once instead of dealing with that.
This got randomly beamed into my head, and it’s bugging the hell out of me that I can’t remember anything else about it. It might’ve been on Itch, but I’m not gonna say that with too much confidence.
