Nice job on putting together a first-person 3D experience for the jam. That alone is a solid undertaking.
The story actually kept me curious. I wanted to keep exploring just to figure out what was going on with the gas station and what the deal was with the place. The mystery element worked well and fit the theme nicely.
Also, kudos on getting voice work in there. That adds a lot to immersion, especially in a slower, exploratory game like this.
The core loop was mostly explore, find something, use it, move forward, which worked well for the kind of experience you were going for. And I saw the note about continuing with further updates. This definitely feels like something that could grow into a bigger project.
Great entry for the jam!
