The game now has enemies and a scoring system. If you’re quick, you’ll be able to catch the helicopter on the east end of the map; in the final version, this will come periodically, and the quicker you are rescued the higher the score multiplier will be. There are also some fun little caves with air pockets and mountain lakes.

You’ll still need to click on it to give it focus.
