Become a king among fidget spinners in Superspin, an agario-esq game in which you gather sparkly crystals with your fidget spinner in an effort to grow bigger and badder.

Guide your fidget spinner around with WASD, and mouse or space boosts at the cost of sparkly crystals you've gathered.

The strategy here is simple: don't be eaten until you are big enough to do the eating. Boosting can also be quite costly, so save it until you really need it.
