Boxy Tumbles

Can you help this box fly through the air? 

Launch the box off of a hill and buy progressively stronger upgrades to go farther. Some upgrades passively affect the box itself, others are items stored inside the box that you can activate with Space and require you to rotate a certain way to best utilize them.

Left and Right Arrow Keys - Rotate
Space - Start attempt and use current item

Try to go over 2,500 meters!
