Hello, I played this game and I liked the style of it although there were some bugs which are expected since it's a prototype, I didn't really know how to solve the 3 digit code but I just randomly got it, over all it was a cool little demo game, good work :)
Appreciate the video
Btw for the lock the note said "Devil's number can helo u out of the room" the devil numbers is 666. The backside of the note also had 666 printed all over the page so that was the hint
Overall nice video!
