For the demo, included level 2 in addition to level 1.
For game, add 'Fixed Daylight' option in the pause menu to fix the daylight so the sun does not move(no night,etc)
For regular day/night cycle slowed down the day and shortened the night period further. Players were frustrated at having to pause for night to pass. May try to fix this later by adding more ambient light at nighttime.
Added labels/instructions to the 'practice course' on the side field. Players don't realize you can jump from the walls, making the game more difficult than need be.
Added simple arm up/down images for Vive controllers to show which direction to point controllers to get thrust in those directions.
