Thank you, TECGOTHICA. ^w^ I appreciate that you enjoyed the atmosphere and I hope you'll be able to beat the demo in your future playthroughs.
Firstly: The game is randomized, items that were there in the first playthrough will spawn somewhere else in the second playthrough.
Secondly: This is something I said to almost every youtube letsplayer that played this game, but matches last around 20-35 seconds. The way you move your mouse (while the match is lit) determines how fast the match will die. If you move your match around the area fast, it will die faster. This was sort-of added to encourage careful exploration because [sometimes] the items blend into the background and you won't notice them at first glance. If you switch to EASY ACTION DIFFICULTY, then your matches will be less affected by your mouse movement.
There is a way to get your match to never burn out.
Thirdly: I don't have a name for that section, so for now I'll call it the [DON'T MOVE] section (even though that's probably taken by Until Dawn™). The [DON'T MOVE] section can have its speed tweaked, but it's tuned enough. Switch to EASY ACTION DIFFICULTY if it's too difficult for you to pass it on NORMAL (rip HARD mode). As for the "get gud", nah- that's all on you. xD (I'm joking btw, but I made it hard on purpose. There is a "tactic" to make it a little easier, but at the same time it depends if you're playing with a mouse or the laptop's touch pad. "Mouse Sensitivity" is, in my opinion, a bad design choice because everyone will take advantage of it to make the [DON'T MOVE] section always easier... but that's just how I see it. If you want the [DON'T MOVE] to be easier, play on EASY action mode and practice there for other modes.)
I hope this info helps, and good luck. :)
