Hey there!
Well, there is a mini-map in-game, but it's an unlockable thing after beating the demo with a highest possible rank. It's mainly useful for finding secrets. I'm not sure if we're going to add a map in the main game by default. It would make things too easy. Plus, as we said in the description, the game is supposed to be kind of hard. Since you're in Purgatorium, getting through puzzles and making progress is rewarding, as well as the exploration and item usage. You have to think and focus on survival, while keeping in mind that you're lost and vulnerable. I think it's kind of good for the scare factor and it keeps players on edge.
Well, you couldn't find the screwdriver, because it was in a different place. A few items are randomly generated around the basement, including key items.
We're contantly thinking how we can make the game more accessible for casual players, but not too easy. We're trying to balance all of the difficulties, so bear with us, while we try to sort this out :D
Also, you have to break something with a pipe near the exit door. Something that's above a 4-digit padlock.
