Pretty nice visual design.
At first I was kinda confused as to what to do. Some text dump would be appreciated at least.
Also you don't need to talk to the scientist. Which makes it a walking simulator. But damn when he started chasing me I was scared s*itless. Amazingly since there is no pathfinding for him he just f*cking phased through the wall which was terrifying XD. Also it wasn't the best choice to add chests there. Took me a while to figure out the keys belong to the door at the end. Or do they? I have no idea cause it was quite linear so I am not sure if I needed the keys for the final door or not.
But I can feel you. I also did a game on my own and its tough so its commendable. Good Job!
