Invert bits to render correctly on browsers which do not render whitespace character correctly

This update inverts the bits so that dots are used for the game's background and empty space is used for the player and the target object (food?). This allows the game to render correctly on browsers which do not render the whitespace character correctly (which seems to be most browsers lol)

Totally understand if this is not wanted, but it is one fix to the problem

Hey @bradenhirschi, just wanted to let you know i noticed this PR, but i haven't had time to review this properly yet.

I have some initial reservations about this approach (i've tried it in the past, and discarded it). But also, i feel i need to really play the game for a while in this mode to really have an informed opinion about it. I'll report back when having done so hehe.

Thanks very much for the PR though; much appreciated :)

No worries, like I said I understand if this isn't the desired appearance. I do think that it is at least a good solution you could offer for browsers where the whitespace character isn't rendered right
