Thank you for playing! I wanted to send you a message with the solution (to avoid spoiling too much here) but I don't know how to DM people in itch.io, is it possible? '^^
I know, that's why I dont ask for the solution just a clue, I want people to play and enjoy it too, so I keep the walkthrough to a minimum. Unfortunately itch haven't got any way to DM, but if you have Discord, you can add me: TheOslaf#4211, I would love to play the game until the end.
