im having a problem when i get to the forest part, is that the end of the demo or is a bug, the game just closes when the loading screen finish

i tried both instaling it with the itch app and downloading to play the app and when i click either of them they just star loading like if they were to open but then nothing happens

for some reason the demo doesnt open to me, is there a bug or something? or do i have to open it in a certain way?
