hi
so, i think u found a bug
(spoliers)
when mya changes into the monster in the hospital and it chases you
you have to walk over a plank to cross a gap in the ground
and if you took the plank before this scene you can't cross nor have enough time to put it back in place
and i don't have a different save from before this moment so i can't fix it unless i play the game from the beginning again, so im stuck
