Altitude Zero - https://store.steampowered.com/app/4839050/Altitude_Zero/

Altitude Zero is a short atmospheric and unsettling horror experience. Pilot an old hot air balloon through a desolate land with one objective: reach mysterious stations and shut them down to stop something that was never meant to awaken. During this journey, you will have to keep control of your hot air balloon as freezing winds and hostile creatures try to bring you down. A paper map will be your only guide, while the burner's light will be your only relief in the darkness.
