Maxed out all the upgrades and dug to the funny blue box on the bottom of the world.
Also, it takes about 21.3 seconds to freefall from the top of the world to the bottom
I NEED MORE
and 33 seconds to fly to the surface from the bottom
That's great haha. I think this game is missing the hostile environment found at the lower levels of the original game. Also the boss battle and story elements.
