Mac version when?

Please change the font in the tutorials it's barely legible 

What if I made it even more unreadable?  >:)  Would you be mad?

just kidding :P the tutorial is already getting an overhaul for the next update (1.0) you'll just have to wait a while for me to finish writing story mode lol


I adore this game. I think my only wishlist item would be a 4-player option to use with Team Mode. Aren't nearly enough 2v2 fighters out there that give the option for pair play.


Would worship if had a demo version. It's making me jealous watching everyone play!



wish i could buy it, i would buy it again if you launch on steam, seriously tho, this has more content than most AAA fighting games, until there, i will keep trying to make my paypal work

i got the game after all, realy good, but it need better tutorials, i know that UI and UX are realy hard thinks to do and i wish this game had a 30 hour campaign teaching every com piece of the game, but this is just impossible, so please break the tutorial in blocks more specific than offense and defense, specialy because of how complex these concepts are, if possible make more like novriltataki guilty gear crash course, if its not possibl, thats fine, your game is great and i would buy it again on steam, just so i can play online thru steam, i think, idk how steam works, either way i would buy it again for the sake of it


Just bought the game and i'm loving it! Really tight controls and a lovely art style. Can't wait til arcade/story mode!


Does this game have online?


is there a comunity discord of this game?

yeah, the link is right beneath the "Default Controls" section :)



Is online multiplayer a planned feature, or is it available through parsec?


I don't want to make any promises I can't keep, but I'm looking into it. For now you can use parsec. ;)

Very fun, I like oversized hoodie girl

Will the game release on steam?

Maybe, but it would be more like a +R or Version 2.0 so it's worth rebuying

Ok, I'm buying here the game in a few days


fun as hell :)


Thanks :)
