Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Good fighting game to play with some of your friends with to either ♥♥♥♥ post or just intensely lab cool combos !
Gemion function, despite the way it currently looks on the outside as of 9/23/2025, has a very deep and solid understanding of what fighting games are and what makes them fun to play. I went into it unsure about how much i would enjoy it, but after i came out I was pleasantly surprised at how well it controlled. I recommend it for people who are pretty into the technicality of fighting games.
this game is truly a gem that was found at the function aka its peak
This game is rough around the edges, but for what it is, it's a lot of fun. If you like the crazy weird fighting game styles of other games like Ultra Fight da Kyanta 2 where freedom is the key aspect of the gameplay, you'll like this one.
This game reminds me of mugen in a wholesome way. Nice mechanical variety among the characters and just the right amount of jankiness. If you are a fan of mugen, I encourage you to support this indie fighting game.
Having fun with it so far. Has that late 2000s/early 2010s fighting game feel.
