its called Gem for a reason
this is how you make a good fighting game some of yall big companies need to take notes
now THIS is a real fighting game
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.
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.
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
