Main Story
A Metroid crashed into Earth, destroying the planet's gravitational field, causing everything to float. Most traditional sports couldn't be played anymore until Rival Inc. developed various technologies to adapt these sports to the new conditions. Rivals is a game based on whimsical interpretations of soccer, tag, and basketball in this zero-gravity world.

Mini-Games:

Zero Ball:

Objective: Score the ball into the other player's goal.
Twist: Players can hold the ball and use their suits to either attract or repel it. Switch between modes using your action key. The movement is a little complicated so you can't score 20 goals at once 😁

Touch Me Not:

Objective: Dodge the Cursed Bot, Mechanoid. If Mechanoid touches you, you receive a curse and eventually die. The more curses you have, the faster you die. You can transfer your curses to another player.
Twist: The number of mechanoid doubles every 30 seconds.

Domination:

Objective: Hold the ball for the longest time to win.
Twist: When the ball is free (white) and touched by a player, they become the owner and start dominating (any color). Other players must catch the owner, not the ball, to reclaim it. If they touch the ball directly, it enters Rage mode (black) and blasts all players touching it.
