What a submission! Love the PS1 graphics, love the design of the world, really enjoyed driving the car and the mini-games (starting up the car, reloading) were great ideas to bring the game to life with the addition of minimal features. I'm seriously impressed you managed to make this for a gamejam, incredible! This is like a Crazy Taxy-Resident Evil mashup, I really enjoyed playing it. The picture-in-picture camera was a very nice addition, though it did confuse me at first: it made me think the survivors were killed at the point that the next survivor was brought into focus. Maybe this could be solved by just writing 'another survivor!' instead of 'survivor at...', that would (I think?) communicate to the player the picture-in-picture is just cycling through available survivors. It'd also have been nice to see in-game what the controls were, now I just had to intuit what buttons to press to enter and start the car, and guide survivors into the car.
At first I also wanted to write that the lack of a map is annoying, but I'm actually beginning to think (like you probably decided) that not having one is better: that forces the player to get to know the map more. If I have more time I can totally imagine coming back to this game to get to know the surroundings more. Really excellently done.
