I survived! Eventually. I ran around and around so many times and thought I'd seen everything, then suddenly I stumbled onto a place I'd never seen before, and beyond it was the TV!
This one is seriously scary, I react to loud noises very easily so games which pair that with some kind of unstoppable killing machine really get to me.
There's a bit of frustration when you see the monster coming for you and you know that your only paths away from it lead to dead ends, so I often ended up running directly toward it so I could restart quicker. Being able to hide in things might be one way to change that, though I'm guessing the demon's current programming has it stalk toward the player and it wouldn't ever leave. The other suggestion I'd give is to have dead ended areas loop around so that it's possible to outrun and loop around the demon to avoid it, but that does lessen how threatening it would be.
Other than that, the game may be simple but it's very solidly made, well done! :D
