Sumo Slam

You control a small, round character on a circular platform. The goal is to shove the other fighters off the edge using your own momentum. You build up speed by moving in tight circles, then release to slam into an opponent. The controls are just the arrow keys, but timing your charges and anticipating the other characters' movements is the real challenge. The game can be surprisingly quick; one wrong move near the edge and you're gone. It feels like a chaotic, weighty shoving match where every round is over in seconds.
