Hi Sioray, thank you for playing my game and for writing such a wonderful feedback! :D
To answer your question...
(For everyone else, beware! SPOILERS)
1)To obtain the TOP LEFT picture, just play the game as a Woman and then don't kill the creature but just LEAVE the cave (you can pick whatever choices and the outcome won't be affected);
2)For the TOP RIGHT pick these choices: ---- I'm a man ---- am I dead? ----go with him ----eat----thank----cook----are you alright?----creature?----say something----everything ok----be kind----tell truth----have you seen yourself----sleep----stay here----kill him
3)For the one below the tob right, choose: ---- hi---- I'm no one---- where..---- go with him---- eat---- thank---- eat raw---- be kind---- tell truth---- start fire---- thanks---- sleep---- enter cave---- don't---- yes---- stay
Hope this helps ;) and if you're still stuck don't hesitate to tell me
Have a great day!
