This game is really, really fun. My advice is to start by upgrading your goggles. In other news, in searching for this game, I learned about "Hedgehog Space."
For any cardinal number K, the K-hedgehog space is formed by taking the disjoint union of K real unit intervals identified at the origin. Each unit interval is referred to as one of the hedgehog's spines. A K-hedgehog space is sometimes called a hedgehog space of spininess K.Word.
