If I could give a critic and bug report.
I think the Siren Head jumpscare could use improvement, the camera just waving back and forth while there's a sinister laugh just makes the jumpscare and death scene look a little goofy. It just doesn't feel like a scary looking jumpscare if I'm honest.
Also for the bug report, it's possible to interact with and pick up the shed items through the walls while being outside and without going into the shed at all, also Siren Head can even get you through the shed walls too.
Aside from my one little bit of criticism and the bug report, the game is very damn good, I played it on my channel a long time ago, and I believe this to be one of the best Siren Head games that was ever made and arguably the scariest Siren Head game I ever played. Here's my own gameplay video of it from a long time ago if you are interested.
