So, I realized that this would probably be pretty good as a horror game as well (rather than fps), but I think it’ll work. 
I thought it would be good to add some collectibles in the form of notes to create a little bit of lore and story for the player. This can be split into two levels (I have an idea for a third level as well), where the goal of the right level is to get to the mansion (with shed location being optional). The left part is inside the house. The goal is to get to the exit. There are two possible exits… one can be reached by navigating the basement (which should be the harder path) and the other by finding a key at the upper floor (with a lot of optional stuff - notes and special monster).
