About this game
SIN CARDS is a horror-themed card game where you must build the ultimate deck to survive the nightmares of the Netherworld.
・Combine strategy and luck as you collect and purchase powerful cards, craft deadly combos, and face off against terrifying monsters.
・Demons gradually grow stronger and more aggressive under the control of Delilah, the sinister voice of the Netherworld, a manipulative and mocking presence.
・Each level introduces increasing difficulty and new mechanics like crafting, mining, and fishing. Craft hero items using resources and strategy.
・Persistent Skilltree, Sin Coin Slots, Roulette-Style Games and Lore Expansions.
・Each new level reveals more lore about the Sin Cards and the demons that inhabit the world. Some say the choices you make reveal the lengths you're willing to go to survive permadeath.

VERSION 1.1 [MUSIC+]
I'm excited to share a few updates and a glimpse into the future of SIN CARDS. Looking ahead, I plan to gradually expand the game into a more open-world experience. To improve the overall atmosphere, I've adjusted the audio direction. While horror remains a key element, having every sound tied to it led to tonal fatigue during gameplay. As a result, the battle music has been refreshed to bring better pacing, or rather storytelling. Each song also tells a different story. You can always adjust the sound volume in the settings. Update Highlights: ・18 new battle tracks added ・1 new enemy introduced (and it’s the first one you’ll encounter!) I’m also aiming to add more enemies, new cards, and dynamic random events in future updates. Thank you so much for your continued support, it truly means a lot. 💬 I’d love to hear your thoughts! Feel free to leave a Steam Review or post in the Discussions. I read every comment, even on the YouTube page. Enjoy the update, and see you in the next one!Read full article on Community Announcements (LIGHT)Patch NotesOfficial

What’s New in Version 1.0: ・Sin Cards can now be completed with the release of the final Zone! As a solo developer, I test everything myself, but bugs can slip through. Please report any issues you encounter so I can address them quickly. Thank you for playing SIN CARDS. The Netherworld is only just beginning to awaken...Read full article on Community Announcements (LIGHT)
