The game requires about 4GB of ram, so if there isn'e enough, it might not work :( If you can't play it with the hardware you have, please contact itchio for a refund. I'm sorry about the trouble!
I found a way around it that may be usefull!! Every couple of dialogs you'll need to save your game and continue on like that, and after every dialog option save just so you don't lose progress (been doing this method to get every ending lol)
