That Gravity Glow

A short Puzzlescript game made for Lowrezjam,  using the theme "Gravity is the enemy".  The jam has a restriction of 64*64 pixels, and I used 60*60 pixels. The game isn't totally finished, but I've uploaded what I was able to make during the jam period.

Controls: 

• Z is undo
• R is restart
• WASD or arrow keys for movement 
• ESC exits to the level select or menu
