This is an awesome concept, and something I'll be interested to see as it expands. You have a nicely crafted environment, especially outside (with whatever is chasing after you in the dark - perfect!), that nails atmosphere.I do have a couple points that I hope you're willing to hear out as you continue development:
- First, as you continue work on this project, I hope you introduce dynamic, rather than static, 'enemy' character models. The static models have a creep factor, but to me, I feel it betrays all the hard work that's been put into building the environment.
- Second, the white door sequence seems out of place. You allude to the story throughout the quest and give clear indication as to what happened, which makes the first 2/3rds of the hallway unnecessary. Perhaps the player could 'relive' the conclusion of the story through the eyes of the father as the white door scene (from the point he comes home.)
All that to say I'm looking forward to seeing this story grow over the course of the coming year, as this could be a unique entry in the horror field.
Best of luck!
