Interesting premise and it's interesting to explore the forest, though the Siren Head is a bit of a let down. It's really slow so after the initial encounter it can't catch up to you.
Pros and cons are down below. Check out my vid (the game is the third there):
Advantages:
1. I love the sound design and different ques for Siren Head.
2. I appreciate the comments that main character does upon noticing strange things.
Disadvantages:
1. Too short!
2. That is very strange that Siren Head just allows you to bypass him. Though, it may be his normal rection. Still, he can stand still while hunting but after noticing a prey, I don't think he would act like that.
Overall:
Enjoyed the game a lot! I can't wait for the full version. I think right now it need a bit more polish. Though, I need to admit that Siren Head became popular because of this game, so thanks so much for creating it!
Hope my feedback was useful!
