If you follow the competitive fighting game scene then the name Rivals of Aether may be familiar to you already; created by Dan Fornace - who previously worked on the Xbox One remake of Killer Instinct - Aether has been doing the rounds at various gaming events following its release on Xbox One and Steam.
Fornace has written a fairly detailed analysis of how the game has done so far, and mentions that the future involves bringing it to other systems - with Switch being the priority:
Right now we are prioritizing the Nintendo Switch as we are currently looking into developers who can help us port the game out of Game Maker Studio so we can release on the Switch.
At the moment, Game Maker Studio - in which Aether is built - doesn't support Switch, which means it and many other titles made using the engine (Hotline Miami, Hyper Light Drifter, Undertale) would have to be ported by other means, which is naturally a time-consuming process.
Hopefully Fornace and his team can find external help to bring the game to Nintendo's machine, but it would be lovely to see Game Maker support introduced at some point. In the meantime, tell us if you'd be interested in playing this 2D take on the Smash Bros. concept by posting a comment below.
