Good game, informative and helpful too.
I liked this game, it was a bit irritating to figure out, but don't worry about it too much and keep trying and you'll get it.
If you want to play this game and get the most out of it, I suggest you don't use a walkthrough. Here's some hints if you want them.
1. The skateboard CAN be avoided.
2. Some doors are locked, don't sit there and try to open them.
3. In order to win the game, you'll need to get an item from the bathroom that isn't the medical kit.
4. All items are required to win the game.
A few tips-
-Every second really does count, don't stop moving.
-Shutting doors will definitely buy you some time when it comes to smoke.
-While you're getting items and waking up family members, put whoever you've already gathered in a closed room away from the fire.
