CarryBot

You are CarryBot: a small hovering robot designed only to carry small metal cubes. However, the lab where you were designed was just a little bit... chaotic. This is probably the reason why you have such an incredibly uninventive name, but the consequences don't stop there - you're also quite useless at your job. The more cubes you carry at once, the slower you get. And, as if this wasn't enough, trying to carry more than 6 cubes will kill you.
