Rivals of Aether is a platform fighting game that was developed and published by Dan Fornace inThe game takes inspiration from Super Smash Bros. Melee and features a tightly balanced roster of 14 characters, each with their unique moveset. The game is played on a stage that can be compared to a platform game level, and instead of a health bar, damage is represented by a percentage. The game has a decently-sized competitive scene and is played at various major tournaments.

The game's mechanics draw heavily from Super Smash Bros. Melee, known for its competitive depth and aggressive gameplay, and tries to improve on them while cultivating its own original dynamics. The game features a parry instead of a classic shield, which can stun opponents if successful, but also comes with a significant recovery period if it fails. The game also includes advanced techniques from different entries of Super Smash Bros., such as wavedashing, Reverse Aerial Rush, and moonwalking, all balanced with competitive play in mind. The game has a unique focus on competitive play, with every stage having an original variation designed for competitive play. The game can be played with two to four players in a free-for-all or team battle mode.
