jarjammed might work if you don't mind Homestuck. The game is a panfandom, glitched session of Sburb, but actually having read Homestuck isn't a requirement because everything is outlined so well. The pace falls at about medium but tends to speed up a little during events and slow down a little right after them. She can stick a Pokémon or two into her kernelsprite. There are slice-of-lifey options and aspects to the game, but it's definitely driven by an overarching plot that's becoming especially important as of late!

Apps'll be open for a week starting on the eighth and that'll be the last app round ever—we aren't at endgame just yet but plot things are making more entries impractical. Bianca here and Lance (both gameverse too) are the only other Pokémon characters, and I'd really love to see May in whichever one of her iterations!

If you have any questions, lemme know and I'll do what I can to help out! ♥
