Cool Game! Cave exploring definitely fits the theme and I love how you repeatedly warn the player to turn back but it is too enticing to keep going in. I got the car ending right away because I had a hunch that was the right thing to do lol.
When I got to the end, I was hoping that there was just something more to make it worth going in. Other similar games that tell you not do too something reward the player for doing the opposite ("Stanley Parable" and "There is no Game" for example). A little more detail there would have been the icing on the cake. Great work!
