  Happy 1 Year Anniversary of Zero-Sum Heart

  Hi Everyone,This is Mari and Jenny from Citreat Studio, the developers of Zero-Sum Heart! We just wanted to pop in to say thank you as we reach the 1-year anniversary of this little game. Zero-Sum Heart, alongside the soundtrack and artbook, it's currently on discount for Scream Fest and the cheapest it's ever been so feel free to jump in :)Here's a little celebratory art, courtesy of Jenny, to celebrate this milestone! (Consider it somewhat of an alternate universe, as The Mighty Witch would probably never deign to dine with and play third-wheel to these two idiots.) Hope everyone is having a great time with your family and friends and eating something warm, as winter is fast approaching! (Or for those of you in the Southern Hemisphere, hope you are having some ice cream :)We developed this game in around 6 months, so it has officially been twice as long as the time it took to make it. This game is important to us, both because it's our debut project as an indie studio, and because it was honestly just super fun to make and seems to have changed our lives in magical ways. As we spent the year chipping away at a much bigger project (more on that to come!), we really started appreciating Zero-Sum Heart more as something small and tight and beautiful.In this year, we've added Japanese, French, and Latam Spanish, all thanks to the love and support from this little community of people who played the game and found something that resonated with them; so they generously contributed their work in helping the game reach more people, and that is sincerely something we've never expected and are endlessly grateful for.So, thank you to everyone for playing and hope you are all having a very nice day

Damn you Steam, give me back my spoiler tags in the visual editor please!We are also going to work with our Nintendo Switch platform publishers to bring this update to our NS version as soon as possible, but that may take a little more time with working with porting and platform certification wait (Btw if you didn't know, Zero-Sum Heart is now on Nintendo Switch, featuring a deluxe version with the artbook and OST yay!)
