A few quick things to get out of the way before I get into the meat and potatoes of the discussion, firstly, repackage your game outside of the development kit. My steam VR is having a mental breakdown trying to figure out what is going on, and the console commands remain accessible unless you package and export the final product. Besides that rather simple fix, I've got an entire list of issues rattling around upstairs, and I'm about to try and empty them in a semi-legible fashion, wish me luck.
PRO'S: Some of the tension building moments are quite good, especially segments involving the "SHADOW" character turning off lights while existing as a 2D SHADOW.
I try not to be overly harsh when it comes to ripping into games; as far as I know, this is your first or second attempt, but I feel like there are grievous, almost inexcusable errors throughout the game, such as.
CON'S: Texture inconsistency, most textures throughout the game have issues rendering the correct brightness, while some objects just stand out almost as if they had a spotlight directly above them, in complete pitch-black areas, some doors and doorknobs are practically invisible. I went out of my way to include all the times I noticed these issues within the video, so they are easy for you to find and fix.
The voice acting was acceptable, but the story was a complete waste of time. An abusive father may or may not be possessed isn't exactly new, but what could be new is a 2D monster that works in shadows, maybe focusing on that instead of a rather strange almost B plot.
Finally, the endings, oh god, the endings. Inventory glitches that waste 45 minutes of my life. While I am more than happy to give leeway to games that attempt multiple endings, there's no reason to include an endless array of red herrings. Ultimately unnecessary items and notes add no context or story and are failed attempts to make the game seem more profound than it is.
If you are going to bait the player into thinking there is a "Good Ending" maybe bother trying to create one outside of a meme, or at least include some form or hint or guide towards actually acquiring it.
Overall I'd say the game is a weird mix of incompleteness and generally feels like playing a buggy mess. A summation of my thoughts can be located in the video version of this that I'll post below. I hope you continue to make games, you have passion, and I think with just a few more tweaks and touches this could be a pretty solid entry into your library.
