Well, I didn't see that one coming!
A well-written little horror short with a simple but well-executed concept. Great use of atmospheric sound and animated visuals which add a sense of style while also nicely capturing the feeling of rising anxiety. Strong use of similes and metaphors!
If I have one minor nitpick, it's that you have to dig into the extras after the end of the game to get the full picture of what exactly happened. Early in the story an "incident" is mentioned, but it's never really brought up again. I think it would be a stronger narrative if the protag's "incident" is alluded to a little more throughout the story - obviously not in a direct spoilerish way, but in a way that leaves breadcrumbs leading you to believe one thing, when in retrospect after finishing the game, you realize the breadcrumbs were leading to a whole other, more horrifying conclusion.
(Sorry if that's too vague to be helpful, I'm happy to explain more in detail in a PM if you'd like!)
