Your heart keeps you alive. I was making a joke

[MatthiasMan]

Oh. I  thought I banned you from being confusing.

[Primrosewarrior]

I'm trying my best here...

[psybox]

i ban you from trying your best.
it has a heart because you had to carry it around the entire level, but they couldn't tell the play-tester that, so they gave it a heart to illustrate the fact that it was a special cube.  needless to say it became a HUGE internet hit without them meaning to.
