Fortunately you can have more than one girl over at once by just inviting two at once with your phone...
Also due to the need for player control either you can be vored by anyone and there be a 2h time skip or you keep control and can't be shrank. Besides, the player has access to everything, even the fountain, so ofc you can vore any character.
Also this isn't made in renpy and that's just kinda obvious. It's made in game maker.
