Sumotori Dreams – It's Like Watching Drunk People Fight!
Check out the video for this game "Sumotori Dreams"
You are one of two blockoid characters. The object is to knock your opponent outside of the circle (sumo wrestling style) or to be the last one standing. The controls are simple, arrow keys move, backspace shoves with two hand, and enter shoves with one hand.
The gameplay resembles a couple drunk guys stumbling around shoving at each other. It's really quite humorous.
It's a small (VERY) download, PC only. If you want to give it a try you can find it on the Sumotori Dreams website.
