I think you really nailed the horror vibes! The rear view mirror gave me anxiety, I just couldn't keep my eyes on the road. I was sure the passenger would do something to me. And of course, they did. Lucky I was wearing two sets of underwear.
Graphics are great, the sound conveys the right vibes. It took a little long to really get going, longer than I was expecting for a jam game. But I think you've got a really cool vision for this! I spoke to the dev on Discord, seems like a cool person too.
