Thank you for the offer, but right now I've only just launched and I'm still getting the hang of the whole production > update cycle. I'm afraid working together with other people right now isn't something I'm ready for.
Having said that, I can absolutely recommend just diving into it by yourself. Ren'Py is a surprisingly accessible and functional tool for building a visual novel. With just a few days of messing around and watching YouTube tutorials, you can get something off the ground.
