Your UP number should be part of the title, see email. This is quite fun once you realise that 'space' is the control! Also there is no way to exit from within the game (honestly i wouldn't count exit as a game control - maybe i need to mention that next time)! With some sound a graphical polish i can see this as an interesting thing. Consider a more... marketing... type image for future submissions. Also several days early, well done.
