What a masterpiece! Certainly it is going to tell a dark, yet great story and I can`t wait to see the full release. There are a bunch to explore and a lot of secrets.
For example, the following secret is relatively easy to find. (Spoiler alert)
You first need to get a crowbar from the store. You can use it to break those supply crates. Most of the stuffs inside are useless blocks of coal, but there are also a few MRE and disks in them.
Then, break all the crates in your dorm. It will take a while even with your crowbar. You will find several bones and a skull in one box. After you break them all, you will find a boarded-up hatch. Use your crowbar again to break the two planks. Then, you can climb down the ladder. You can find a Van Gogh`s painting, an mre and a notebook down there. Read the notebook then.
