Nice game, I give always extra props to anyone who puts the effort in to make a beginning cinematic, let alone voice over for it. I feel the game was bit ambitious for the one week game jam, but aren't we all lol, there is lot of small nitpicks to hone out, but there is also lot of intrigue here too. Firstly, the visuals were nicely executed, I took note of you got the 2D lighting to work and the layered look has a great feel in my opinion, even just using the same spider web on foreground and background got great uses here, and I feel there is lot of potential for horror too. The sound design here was my highlight I think, first time the whispers came I had that genuine dread overcome me, bit sad that there was no pay off (or rather the whispers proved quite fast that I didn't need to care for them), but I liked them. The story being open is fine and all, but I do feel it ended abruptly, but maybe that just means there is more to come, so who knows. But the story coupled with the rather extended walking aspect (backtracking and all), got me out of the experience a little.
Overall though, despite it all, good work on this, I hope you continue developing this as it seems you have good puzzle-narrative laid out for a fuller game!
