About the Game

You are a company employee who works late into the night. You return home to your normal daily life, just like always. However, while casually playing a video game, you are suddenly sucked right into it! Let's find the answer to why you got trapped in this game.

Somnivium is a Roguelike Deckbuilding game where strategy meets limitless creativity. Collect cards, build your deck, and fight your way through a mysterious digital world.

Key Features

  • Strategic Deckbuilding: Choose from over 30 unique cards to build your ultimate deck. Manage your energy (Cost), calculate attack damage, and defend against incoming monster attacks.

  • AI Card Fusion System: The core mechanic of the game! Combine any two cards to create a brand-new "Fusion Card". The game utilizes Local AI to generate unique art illustrations for your fused cards in real-time.

    (Note: Image generation time depends on your hardware. We recommend avoiding the AI feature on the Fusion screen for older PCs to ensure smoother gameplay.)

  • Turn-Based Battles: Engage in tactical battles against various enemies, from Slimes to Skeletons. Every turn counts—draw the right cards and use your skills wisely to survive.

(Note: This game was developed within one month by two novice game developers. We apologize for any bugs, but we hope you enjoy the unique mechanics we've created!)
