Guys! You won't guess what happened! RenPy update broke the game. Old code is interpreted in some weird way don't displaying videos lol. But no worries. Art that takes like 75% of time is safe :) That means now I have to refactor the code which is good because it was buggy anyway <3
UPDATE: After investigation I learned it has something to do with Python version update. No a big deal anyway (I hope)
