Hey I just played this game and it was really fun! I also played your previous game, also a great one. But I've run into a really bad error with your latest build of the pc version.
SPOILERS!
It goes into this error loop around the scene when the stalker tries to enter through the backyard. Whether I kill him or just knock him out, once I'm outside getting the bullies (again both killing and knocking out options were tested) I finish off the last one with multiple error screens showing then Antonio coming up and giving me the same dialogue from before the stalker came in. Then the stalker comes in again and it all repeats.
I actually can't finish the game due to it. The only ending that worked was the one where the stalker takes Antionio and when stalker takes me.
