It's neat to see a jam game with some story like this! I initially ran into the same problem as Gecko_Deepwood: obviously there's only so much you can do in a weekend, but there really needs to be some clue that the character is moving at all. Some background objects in the level (or even just a texture on the floor) would help, but more than that I wonder why the phone couldn't have been visible on screen to begin with. The walk to reach it isn't particularly eventful! I found the drive later on an even bigger problem: some road markings would do wonders to indicate that the car is actually moving and hasn't hit an invisible wall of some kind. Art-wise I quite liked the pixel characters but the AI-generated stuff looks pretty uncanny. Still, simply getting a full game done in 48 hours is hugely impressive, especially if it involves multiple styles of gameplay as this does.
