Interesting idea, I have played solo and I navigate a little bit around.. I press F and B but was quite hard to understand where I was and where I have to go.. maybe you can add some advice or sign to follow at beginning
You might be right that the purpose is a little unclear at the start, basically you just have to find an exit, it'll be obvious when you find it. I do recommend playing the game with others as well though! Thanks for the feedback!
