Dude! I love this! Every game you make has this specific mood and style. I'm always excited to play them. I also enjoyed the Majora's Mask reference. The only thing I would suggest maybe is the "hint" block. As much as I needed it at one point, I felt like it took me out of the tension a little. Is it on purpose? like the "overlords" put it there as part of the experiment? Anyways, keep making these gems, and I'll keep playing them! I really want to make a fan game of this concept, I'm a little obsessed with it now lol.
btw It legit took me 20 mins of playing it to realize the opening in the fence trigger haha. I felt dumb.
