Note: Dead PvP game
This game contains no meaningful single player content. There are no available servers and no player population. This game cannot be played as intended.

This extremely badly made 2D arcade fighter-versus has a "skater boy" theme, and I do need to explain that theme because the graphics are so bad it's hard to tell what the lazy blobs on the screen are supposed to be. Think of this as Street Fighter but so badly made even Temu wouldn't try to sell it as a knock-off.

So, Rainbowcore Hypernova is a dead PvP game. Why did it fail? It's video game autopsy time!

Almost every PvP exclusive game on Steam fails. Only a tiny proportion of them "go viral". This game failed for many of the same reasons those others fail. The chief of which is the developer thinking that their game will "go viral" without actually creating any reason for it do so.

Competition amongst PvP centric games is extreme, and there's only a finite player base to appeal to. This game failed to reach any kind of critical mass and died as a result. Let's go into some of the reasons this particular game failed to appeal to gamers, despite the zero up front cost.

First and foremost, there's no meaningful single player content. The developer gambled that other players would be an acceptable substitute for adding storytelling, level design etc to the game. They lost that bet.

Without a huge community of players or single player content to add a lasting value to the game, the game dies.

Developers must learn that other players are not an acceptable substitute for adding content to a game.

The graphics here are particularly awful, so bad that it actually stands out as one of the worst looking games on Steam. Quite an accomplishment. It's a big contributor to the failure of the game to attract gamers despite having no up-front cost. Gaming is a primarily visual medium, and if developers want to succeed, they must understand that it's not an area for compromise.

This is "free" enough, at least you won't be expected to spend any more money after you download this, but just because something is free doesn't mean it's good.

Despite having no up-front cost, this failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at just a dozen or so concurrent players, and now there's basically nobody playing it. Even though it's free. This is a dismal public reception, but it's easy to see why gamers rejected it.

Bearing in mind that free games don't add +1 to your game collector count, should you bother adding this to your library and downloading it?

Not this time. This isn't worth downloading. While this won't cost you any money, you get what you pay for, and sometimes, even when the game is free, it's still not enough.

6/10
Its an entertaining few nights of fighting but the menus are impossible to maneuver on keyboard. I'd say it's pretty good for the most part. Attacks are all equally broken, blocking is a tad wonky, and the user interface can only be accessed by controller. My only problem is the controller thing.
