For anyone who is stuck or struggling in this game, here is the guide for Tweedledee and Tweedledum chapter in the game. or Dee and Dum.
For Dee: pick “she feels Dum is jealous of her.”
For Dum: pick “she is tired of being seen the same way as her sister.”
For the solution: pick “Dum should explain why she feels this way.”
It only took trial and error blood sweat and tears and like 30-40mins to figure out but I love this game!!
