Interesting concept. nothing at all seemed to happen in the 1st level so I skipped around after trying it a couple of times. Maybe I missed something?
I love art on the spooky lad who showed up in a later level, as well as the animation ("best quality: his wiggles"). though I'm not a fan of jump scares, so I'm glad my instincts told me to turn the sound down, or i would have been much too frightened to play any more games.
I don't think I could personally handle playing more of this, but I bet it could be enjoyed by many fans of the modern-classic genre of "manipulate objects at certain intervals to prevent a scary jumpscare" games.
