I love the aesthetic of this so much the PS1 style looks incredibly good, and the intro cutscene is fantastic.
I enjoy the core gameplay loop and love all the little details like the taxis driving frantically, hitting the cars with the zombies all the different areas to explore. Theres a lot to love here!
I think the two biggest issues by far is the lack of a map/mini-map and how dark it is. I know the game being darker and at night helps the atmosphere a lot but it is just a bit too hard to see whats in front of you. I accidentally drove off a cliff at one point cause I couldnt see that the elevation changed cause of how dark it was.
There is a lot of cool things here, and I'd love to see you develop this PS1 aesthetic further with other projects!
