I couldn't find a .exe file? which means it might be reliant on the user having pygame installed. Luckily I did but I don't think you should rely on that.
I figured out who the killer was I think but I had no idea where to go from there. The cars seemed uneccessary and really annoying because you can't walk on the sidewalk in some spots (or the cars still hit you on the sidewalk) and sometimes when I was trying to go to a new area a car would spawn right ontop of me as I was trying to leave (or I would spawn right ontop of a car as I entered). The story is cool, the graphics are cute overall 7/10
