I'm KuraiHaru, and for the past few years I've been slowly working on a game called Zero Synapse.

This is my first game, and honestly, I'm still learning how all of this works. I'm currently studying systems engineering, and I'm very much a beginner when it comes to coding.

I also want to be transparent about something: AI played a big role in helping me build this demo, especially on the programming side. I'm not going to pretend otherwise. As someone who is still learning, it helped me understand problems, fix things, experiment, and move much faster than I would have been able to on my own. Without that help, I probably wouldn't have reached a playable demo this soon.

But after a lot of ideas, testing, mistakes, reworking things, and probably way too many broken builds... it's finally here.

Zero Synapse is a small roguelike deckbuilder built around one main idea:

You can fuse your cards.

Instead of just building a deck, you can combine cards together to create new interactions, strange combos, and, if everything lines up correctly, some pretty ridiculous amounts of damage.

I've tried my best to keep the current demo balanced, although I'm sure you guys will find combinations I never expected.

For now, the demo is available on itch.io, but if the project keeps growing, I'd love to eventually bring it to Steam and other platforms.

You can play it here:

And that's pretty much it.

This is my first time putting one of my own games out into the world, so if you decide to try it, I'd genuinely appreciate any feedback you have — whether it's about the gameplay, balance, UI, bugs, card combinations, things you liked, things you hated, or ideas you think could make the game better.

Every comment helps me improve the game and learn as a developer.

Thanks for giving my little project a chance.

I hope you have fun breaking the game with ridiculous card combinations.
