Hey, this was pretty cool!
The introduction sequence of figuring out you're chained to the wall, and then having to try and find items within arms reach really blew me away with how novel it was and got me hooked and immersed into the horror experience you've cooked up! Yeah, I'll admit that everything beyond that intro was a bit cliche and I could easily tell how it was going to go: I kept saying "welcome to the family, son" whenever I walked to the front door and sure enough, it happened, haha! But still, being able to sneak through the house and look through drawers and everything was neat and it all felt well-crafted overall.
If I was to offer some feedback, it'd be:
*I examined the soda and the character suggested to drug it. This is fine, but in my current state where I was still looking for exits, you'd think the character would just be focused on running away, and it'd only be after they realize there's no way out to try something else like that. Just a bit of a sequencing issue, I suppose.
*The place where you'd put the mouse to interact with an object could be really awkward sometimes in its placement. Like, I'd be pointing at a door knob and nothing would come up, but if I point at the center of the door, now I can interact with it. I did play it in Firefox, so maybe this was the bug that was mentioned? I didn't have any other problems, though.
*I wish the game had more interactions to not only give the environment more life, but also explain some odd behaviors. For example, I'm trying to interact with the open windows to escape, only for nothing to come up. It'd be nice if maybe the character would say something like "I'm too weak: I don't wanna risk jumping out and breaking my neck" or something like that.
Very promising stuff!
