if i were you, i would look back through the project and see which part of it the girl did, and when you next see her, show some positive validation and express how you liked the work she has contributed, perhaps mention something specific. if there was something that you dont agree with, let her know about it and ask her to elaborate, then of course you transition away from the project.
after you have built some attraction and rapport, ask for her number again. would be abit weird if you tell her that you already have her number from before.
hope that i have helped. happy gaming dude
