SOMEONETOFORGETABOUT'S PROFILE

So, I started thinking on starting to make videos reviews (still nothing as of yet) about obscure/old RPG maker games. I decided to use the MasterList of Old RPG Maker games (https://rpgmaker.net/forums/topics/22883/), since I thought it would me interesting. So on the MasterList there was game whose title caught my attention (there were other games outside of the one I am talking about) so there Dementia Praecox that caught (like I said before) my attention (because of my interest of mental illness and mentally ill people) so I downloaded the game from the link in the MasterList and I started the game (after unzipping the file), but when I started I just could move around the camera, and I have zero clue on what to do, I move the camera over the map for like five minutes and I have no idea on what to do. Help is appreaciated, thanks. Also sorry for me mking you lose our precious time with this
