SIDE NOTE:
i've noticed that many games include gameplay instructions in the text below the web player or the download link. (yours is actually quite reasonable compared to others that literally describe the controls and objective). i feel like maybe this goes against the spirit of zero UI. it's just my opinion though; i'm not sure how the judges will view that. (just to be clear, my game totally breaks the zero UI restriction. I've got instructions and menus littered throughout my game. i pretty much gave up on having no UI, so I appreciate games like yours that attempt to follow the theme.)
