Notes from Jane:
Lost genuinely scared me, and I think that's one of the best things I can say about a horror game made for a jam. It doesn't need particularly high-fidelity art, because the lighting is so effective at what it does, and more importantly, the sound is. The game *sounds* scary - the staticky fizz and low buzz of nearby enemies are effective, and pay off tenfold in the shock ending. Awesome job all around!
For more critical notes, I'd say that the sword doesn't work the way you intended it. It only shows up properly one in five clicks, even though the hitbox works every time. I was able to work around it to finish the game, but it was frustrating in a way I don't think was intentional. Same with corridors that are entirely empty of purpose-- better at the end than the start.
