I think I just need to communicate better that too much running is basically an instant death because he is tracking you and hears you. I have learned so much about level design in the last 24 hours from watching people play the game. This guy is the only person to pay the game as I saw in my head. He might be the first person to enter the building though the intended path. I'm thinking of ways to get more people on the right track and help people get over that initial hump. Thank you for the feedback! No monster AI nerf just yet. The full game will have safe rooms double as checkpoints and allow for the player to have ways to escape the monsters grasp. I think the high difficulty of the demo helps condense all the feelings of what I want the full game to feel like but in under a few minutes.
It's just the demo version so if some players can't beat it, that's totally fine. The full version will be a bit more forgiving because I want everyone to be able to get through that version.
Again, thanks for the feedback! This is the exact type of thing I was looking for. I would love to hear from more devs.
